BASIC ELECTRICALCONNECTION PRINCIPLESBasic Factors:The basic factors which influence the designand performance of pressure wire connec-tions are as follows:
1. Creep2. Surface Oxide3. Corrosion
A fourth factor, known as thermal effects, isalso a consideration, but due to the technicalnature and length of the topic, it will not bediscussed in this publication.
At the outset it should be pointed out thatthese factors give rise to much more difficultproblems in connections involving aluminumconductors than those encountered in copperto copper connections.
CREEP (COLD FLOW)Creep is the cold flow of the metal underpressure, and it continues until the pressurereduces to a value at which any further creepis negligible. Creep properties depend on theparticular metal or alloy and on its hardness;alloys having less creep than pure metals,and harder metals have less creep than softmetals. In a typical connection, the conduc-tors are generally of pure metal and often ofsoft temper and therefore, subject to consid-erable creep. In addition, the condition isfurther exaggerated when aluminum is theconductor as compared to copper, since itscreep rate is many times that of copper.
Effect of Creep: Figure 2 shows typicalcurves of total contact resistance plottedagainst total contact force. Curve A showshow the contact resistance continuallydecreases with increasing contact force.When the full contact force F1 is reached, thecontact resistance reaches the low value ofR1. In general, the full tightening force on aconnector greatly exceeds the maximum forcefor which there is no appreciable creep.Therefore, the force will gradually settle downto a value after which there will be no furthersignificant creep. Fortunately, however, theresistance does not climb back up along curve
A, the tightening curve, but instead it follows anew curve B, the relaxing curve, along whichthe resistance changes very little, until theforce relaxes to a value such as F2.
Admittedly, the point of "no appreciablecreep" is difficult to define. For pure metals,especially in the soft state, there is alwayssome creep, even at very low pressures atroom temperature. However, we do know thatthe pressure required to produce the samecreep rate is several times greater for copperthan for aluminum. Thus, to permit the samecontact force F2 for aluminum and copper,the contact area A required for aluminum canbe expected to be considerably greater thanthat required for copper. This explains whythe contact areas for connectors for alu-minum must be considerably greater than forcopper, and why many light duty connectorsfor copper are entirely inadequate for alu-minum, even when specially plated and whenrecommended compounds are used on thecontact surfaces.
Relaxation: Relaxation of pressure due tocreep, or for any other reason, would be amuch more difficult factor in a pressure con-nection were it not for the relationship ofcontact pressure to contact resistance on therelaxation curve as shown in Figure 2. It isfrequently observed that some time after thebolts of a clamp type connector are tight-ened, the bolt tensions are relaxed apprecia-bly. The question arises as to whether it isnecessary to retighten the bolts to theoriginal torque value. In a properly designedconnector, retightening is unnecessary sincethe contact resistance should increase verylittle due to the relaxation of pressure, asshown by the relaxation curve of Figure 2.
This fact is largely responsible for thesuccessful operation of a compression con-nector. The application of the compressiontool applies very high pressure, establishingvery low contact resistance. The removal ofthe compression tool releases a very largeproportion of this pressure, and creep furtherrelaxes this pressure. Fortunately, the contactresistance increases very little due to thispressure relaxation.
Contact Force: The previous analysis showsthat the total contact force largely determinesthe contact resistance. Thus, to achieve thedesired low value of contact resistance, theproper size and number of bolts in a clamptype connector must be supplied, and thecompression tool must apply the proper forceto a compression connector. In addition, theconnector must be designed with sufficientstructural strength, contact area, and
resilience, to assure that the contact forcecannot relax beyond the point where contactresistance begins to rise appreciably, asshown in Figure 2.
SURFACE OXIDEThe contact of pure metallic surfaces cannotbe assured in practical connections. Surfacecontamination must be expected, especiallysurface oxidation. These surface films areinsulators as far as contact resistance is con-cerned, and they must be broken to achievemetal to metal contact to make an adequateelectrical connection. The difficulty of break-ing the film depends on the nature of the film,its thickness, and the metal on which it isformed.
Copper oxide is generally broken down byreasonably low values of contact pressure.Unless the copper is badly oxidized, goodcontact can be obtained with very little or nocleaning.
Silver oxide is even more easily broken downby the contact pressure; and since silveroxide forms less readily at elevated tempera-tures, silver contact surfaces are preferredover copper when used for higher tempera-tures. For this reason, it is considered goodpractice to silver plate copper contactsurfaces that must operate at temperaturesover 200 C.
On the other hand, aluminum oxide is a hard,tenacious, high resistance film that formsvery rapidly on the surface of aluminumexposed to air. In fact, it is the toughness ofthis film that gives aluminum its good corro-sion resistance. The oxide film that formsafter more than a few hours is too thick andtough to permit a low resistance contact with-out cleaning. The aluminum oxide film istransparent so that even the bright and cleanappearance of an aluminum connector is noassurance that the low contact resistancecan be attained without cleaning.
In addition to the necessity for cleaning theoxide from aluminum, the surface should becovered with a good connector compound toprevent the oxide from reforming. Commonpractice is to clean the surface with a wirebrush or emery cloth. The compound shouldbe applied immediately after cleaning, or thecompound should be put on first and thesurface scraped through the compound.Present practice is to scratch brush dry andto apply the compound immediately there-after. This allows a more thorough job ofcleaning the conductor.

Contact Compounds: Petrolatum or No-Oxid are good contact surface compoundsfor aluminum, but BURNDY PENETROX A,a petrolatum type compound containing zincdust, has the additional advantage of assist-ing in the breaking down of the contact resis-tance. How this is accomplished is notcertain, but it appears that the zinc particlesof PENETROX A probably act as currentbridges in the breaks in the oxide film. Formore complete information about the PENE-TROX line of compounds, refer to theAccessories Section of this catalog.
Interstrand Resistance: The high contactresistance due to the oxide on the strands ofan aluminum cable may be responsible for apoor distribution of current among the strandson the cable. Thus, the outer strands maycarry much more than their share of thecurrent and overheating of the cable mayresult. Tests have shown that even on newcable this effect of interstrand resistance canbe considerable unless a good contactcompound is used. The clamping actiontends to break down the oxide and force thecompound between the strands. This is par-ticularly true of compression connectors dueto the very high unit pressures developed.
The most effective way to break down inter-strand resistance of aluminum cable is to usecompression connectors filled with a com-pound having zinc particles. Then, when theend of the cable is inserted in the connector,the compound is forced between the strandswhere it very effectively breaks down theinterstrand resistance upon application of thecompressive force.
Plating Aluminum: Plating the contact sur-faces of aluminum connectors will prevent theformation of aluminum oxide. Electro-tin,cadmium and zinc platings have been usedfor this purpose. However, the use of a platedaluminum conductor, does not make it lessnecessary to scratch brush the aluminumconductor, nor does it reduce the need for agood contact compound. Additional problemsare introduced due to the plating onaluminum which render it of very doubtfulvalue over the proper use of bare aluminum.This will be more fully discussed later.
CORROSIONThe electrical conductivity and mechanicalstrength of an electrical connection mustremain stable under the deteriorating influ-ences of the environment. This deteriorationis corrosion. It is the electrolytic action ofmoisture and other elements of the atmos-phere in conjunction with the metals of the
connection. If the conductors and connectorsare of copper or a corrosion resistant copperalloy, corrosion is usually a minor factor.However, it is a very vital factor if aluminum is involved.
If moisture can be kept away from the con-nection, corrosion will not be a factor. Theelectrical connection of a high voltage spliceon insulated cable is generally free fromcorrosion since the taping must be moisture-proof. Similarly, taping may be used to avoidcorrosion on bare cable, provided it excludesmoisture. It is difficult to get a good tape sealto the conductor itself, especially on strandedcable. If moisture does penetrate the taping, itwill not dry out as readily as if the joint wereuntaped. Various plastic materials are avail-able today for covering low voltage connec-tions or for bare conductor connections onhigh voltage. Unless such coverings are completely moisture-proof, it is better to rely on installation with a good contact compound, using a connector designed to resist corrosion.
Galvanic Action: Whenever dissimilarmetals are in the presence of an electrolyte, adifference in electric potential is developed.One metal becomes the cathode andreceives a positive charge. The otherbecomes the anode and receives a negativecharge. When these metals are in contact, anelectrical current will flow, as in the case ofany short-circuited electric cell. This elec-trolytic action causes an attack of the anodicmetal, leaving the cathodic metal unharmed.The extent of the attack is proportional to thestrength of the electrolytic current, which inturn is proportional to the electric potential difference developed.
The magnitude of the potential differencegenerated between two dissimilar metals canbe seen by the position of these metals in theelectrolytic series. Figure 3 is such a series.When two metals are in contact in an elec-trolyte, the one higher up in this series is theanode, the corroded metal, while the onelower is the cathode, the protected metal. Thefurther apart the metals are in this series, the greater the electrolytic potential differ-ence, and the greater the attack to the anodic metal.
Note that copper and aluminum are quite farapart in the series, copper being cathodic andaluminum anodic. Hence, when aluminumand copper are in contact in an electrolyte,the aluminum can be expected to be severely attacked.
Crevice Corrosion: Electrolytic attack canalso occur between like metals due to aphenomenon known as oxygen concentrationcell or crevice corrosion. Since oxygen isnecessary for corrosive action, a variation inthe concentration of oxygen where a metal isexposed to an electrolyte will generate adifference of potential, and cause a corrosiveattack in the oxygen starved area. Thus,since an electrolyte in a deep crevice is freelyexposed to the air at the outside, the concen-tration of oxygen will be greatest at the mouthof the crevice. Then corrosion can be expect-ed to occur in the crevice remote from thesurface. Crevice corrosion can be preventedif the crevice is filled with a compound toexclude moisture. Thus, within the contactgroove of an aluminum connector containingan aluminum conductor, there will be numer-ous crevices in which corrosion will takeplace unless a good connector compound isapplied during installation. Copper, being amore noble metal, appears to be much lesssubject to crevice corrosion.Corrosion Testing: The effectiveness of anelectrical connection to resist corrosion canbe tested in the laboratory under conditionsdesigned to greatly accelerate the naturalcorrosive conditions of actual service. Themost widely accepted means is the standardsalt spray chamber. In this chamber the spec-imens are placed in a salt fog made by atom-izing a 20% salt solution at 100 deg F.
FCI - BURNDY Electrical as well as othermanufacturers and utility companies, havedone a great deal of testing and a consider-able area of agreement has been reached.There are, however, minor differences in recommended practices. The problem is concerned with aluminum and aluminum tocopper connections since the effect of corro-sion on copper to copper connections is far less serious. Let us study the recommendedpractices.
Aluminum to Aluminum Connections: Forjoining aluminum to aluminum conductors,there is little disagreement that an aluminumbodied connector is the proper choice, sincethis obviously eliminates the galvanic corro-sion of dissimilar metals. However, even inthis case, care must be taken to preventcrevice corrosion and to select an alloy of aluminum for the connector body that is freefrom cracking due to stress corrosion.
Aluminum to Copper Connections:Similarly, for joining aluminum to copperconductors, an aluminum bodied connector isthe best choice since it prevents galvanic

corrosion of the aluminum conductor, themost vulnerable element to attack in the con-nection. Realizing this, BURNDY initiated aresearch program aimed at finding the bestway to make an aluminum connector suitablefor joining aluminum to copper conductors.This led to the evolution of the MassiveAnode Principal of connector design for join-ing conductors of dissimilar metal. On thebasis of this principal, properly designed, all-aluminum connectors became available foruniversal use in joining aluminum to alu-minum or aluminum to copper conductors.
Massive Anode Principle: By making thealuminum connector massive in comparisonto the copper conductor, when the copperconductor emerges from the connector, theelectrolytic current density over the exposedface of the aluminum connector is greatlyreduced. This is schematically represented inFigure 4. Since the rate of corrosion is direct-ly related to the current density on thesurface of the anodic material, the relativelylarge face of the aluminum connector willsuffer only minor attack.
In addition, because the aluminum connectorbody is massive in the region where the cor-rosion occurs, the small loss of metal causedby corrosion is insignificant, even after longperiods of service. Furthermore, the connec-tor design should be such that clamping bolts,and areas of high stress which provide struc-tural strength, are not in the regions subject togalvanic attack.
The effectiveness of this theory has beenamply demonstrated in salt spray corrosiontests in which the connectors were subject to1,000 hours in the salt spray fog with onlyminor corrosive pitting adjacent to the copperconductor, as seen in Figure 5. In addition,the aluminum conductor was completelyprotected, and the joint resistance remainedvirtually unchanged. The test involved a widevariety of sizes and types of connectorsshowing the effectiveness for small serviceconnectors as well as large power connec-tors. Figure 6 shows a large all aluminum
clamp type T connector installed on 312"diameter copper run and 750MCM aluminumtap. The figure shows this connector openedup after the 1,400 hours of the salt spray test.Note that the contact surfaces are bright andclean and the only evidence is minor pittingalong the faces adjacent to the copper.*It should be emphasized that a goodcompound should be used on the contactsurfaces whether aluminum or copper is usedin an aluminum connector.
Position of Conductor: A properly designedaluminum connector for joining aluminum tocopper must provide adequate separationbetween the conductors to prevent electro-lytic attack on the aluminum conductor. Eventhen, it is good practice to install thealuminum conductor above the copper con-ductor if possible. This will prevent pitting ofthe aluminum conductor due to copper saltsbeing washed over the aluminum.
Plated Aluminum Connectors: Plating hasbeen used as a means to make an aluminumconnector suitable for copper conductor.Such platings as copper, zinc, tin and cad-mium have been used. The plating ofaluminum is much more critical than plating amore noble metal such as copper. In addition,a preplate, usually of copper or brass, must be applied, thus introducing numerous metals and further possibilities for galvaniccorrosion.
To be effective in reducing galvanic corrosionbetween the copper conductor and thealuminum connector, the plated metal mustbe closer in the Electrolytic Series to copperthan is aluminum. It must therefore, becathodic to aluminum. Since porosity andminor scratches are always present, galvanicaction can be expected in the presence ofmoisture, resulting in attack of the aluminumunder the plating. Corrosion tests revealattack in the form of a mottled appearanceand flaking of the plating.
In addition, the presence of plated metal cancause galvanic attack of the aluminum con-ductor, thus reducing the protection offered tothis conductor in an aluminum connector.
Cleaning and the Use of Compound: Itshould be emphasized that when aluminumconnectors or conductors are involved,proper cleaning of the aluminum and the useof a good connector compound, such asBURNDY PENETROX A, are essential fortrouble-free service. BURNDY, as well asother manufacturers, provide the contactgrooves with a coating to make it unneces-sary to clean the connectors, but in all cases,

the aluminum conductor should be cleanedby means such as scratch brushing, andimmediately coated with the connectorcompound.
To simplify the application of the compound,and to assure its use, almost all BURNDYaluminum connectors, except the large clamptype substation connectors, are suppliedfactory filled with PENETROX compound. Forthe tubular compression connectors, thetubular barrels are sufficiently filled withPENETROX and capped. For other types, thecontact grooves are filled with PENETROXand enclosed in plastic packaging in aprocess called Stripsealing.
Clamp vs. Compression: In general, acompression connection can be expected tobe more corrosion resistant than a clampconnection. The high pressures applied in acompression connector more effectively sealthe contact against the penetration of mois-ture. The tubular sleeve of a compressionconnector has no side openings such as existin clamp connectors between the clampingmembers. On the other hand, the clampconnector can be made more corrosion resis-tant if the conductor grooves conform moreclosely with the conductor contour. Thus aclamp connector made to accommodate awide range of conductor sizes cannot beexpected to be as corrosion resistant as onedesigned for one specific conductor size.Nevertheless, the differences in effectivenessof various designs can be minimized if a goodcontact compound is used.

HARDWARE DATARECOMMENDEDTIGHTENING TORQUE
The hardware used in connectors must becompatible with the connector material, havehigh mechanical strength and be corrosionresistant.
Copper alloy connectors have hardwaremade of DURIUM, which is BURNDY'strade name for silicon bronze alloyASTMB99. This material was first introducedby BURNDY in 1927 for use in outdoor con-struction, and today, is the standard through-out the industry.
Aluminum connectors generally have alu-minum alloy hardware. The bolts are 2024T4and anodized to resist corrosion. The nuts are6061T6, which is resistant to corrosion
and does not require anodizing. Bolts arelubricated to eliminate galling and to provideconsistent clamping forces.
The size material for clamping hardware areselected to provide the required force whentightened to the recommended torque. Toreduce or greatly exceed the recommendedtorque can adversely affect the performanceof the connector.

* These diameters are often employed by purchasers for communication lines BUT are not inthe American Wire Gauge (B & S Wire Gauge) series, as are the other diameters listed.
The designation "Inch" is the approximate diameter in proper fraction of an inch. The designation of "AWG" is a combination of the number of wires each of the American
Wire Gage size indicated by "No."* Diameter of circumscribing.** Breaking loads of 7-wire and 19-wire conductors are taken as 90% of the sum of the
breaking loads of individual wires; breaking load of 3-wire conductors is taken as 95% of the sum of the breaking loads of the individual wires.

This catalog uses the new, BURNDY simpli-fied overhead lines die set catalog numberingsystem, based on Die Index numbers and letters.
The Die Index numbers are marked on theconnectors and die sets. Where a die set hasmore than one Die Index, the catalog number
will generally be the lowest number assignedor all indexes may be marked.
The Die Index numbers and letters in thisconversion chart are arranged in numerical oralphabetical order.
To determine the new catalog number for olddie sets, cross reference the Die Index on the
connector, or the old die set, with the DieIndex shown on the chart. The new die setcatalog number or letters appear for each toolin the previous table. NOTE: Many "A" diesare available. Contact the factory. Thegage column lists quality control inspectiongages for the corresponding die index.
