C O M P A N Y P R O F I L EAberdare Cables, a member of the Powertech Group, is a leading African manufacturer of cables anddistributor of electrical accessories. With manufacturing sites in three provinces of South Africa, andoffshore operations in Mozambique, Portugal and Spain, Aberdare Cables manufactures an extensiverange of electrical cables for application in power transmission, power distribution, rail, petrochemical,mining, ports, airports, wholesale, construction and domestic building environments. Aberdare Cablesprides its self on its ability to identify and satisfy customer needs through development of innovativeproducts; unique, cost effective cable solutions for a wide range of industries. This and their extensiveproject experience make them the supplier of choice for cable, electrical accessories (switches, sockets,circuit breakers and reticulation) and special cable projects.
Aberdare Cables pursues on-going technology development programmes, and through active associationwith its local and overseas affiliates, continues to remain at the forefront of technology.The company hasbeen recognised internationally as a pioneer in cable advancements. Aberdare serves on a number ofSABS and International ElectroTechnical Commission (IEC) cable working groups. As much as ten yearsago, in a move towards facilitating the provision of electricity for all countrywide, Aberdare Cablesdesigned products with an emphasis on cost efficiency of electrification.To this end, Aberdare created itsElectrodac range, which is aimed specifically at facilitating rural electrification by lowering the cost ofelectricity delivery. More recently, in accordance with Siemens specifications, Aberdare produced anunarmoured cable, with stringent fire characteristics, that was designed to reduce the propagation of fireby cables.This cable is used at Eskom's open-cycle gas turbine generators at Mossel Bay and Atlantis.Tocater for international markets, Aberdare introduced fire survival cable with stringent properties that allowcontinuous operation and circuit integrity for extended periods during a fire.
Aberdare Cables is a forerunner in the industry with regard to quality. The manufacturing, qualityassurance, testing and research resources of Aberdare are of a world-class standard. In fact, the companywas one of the first companies in South Africa to be awarded the South African Bureau of Standards(SABS) Quality Assurance Certification, and has been ISO 9001 compliant for many years. AberdareCables is UL listed and has Basec QA accreditation.
Aberdare has embraced the empowerment concept. Today, Izingwe Consortium owns 30% of thecompany and the company has assisted in the development of a number of black enterprises, such asDRUMCO, the company that makes Aberdare Cable Drums. At Aberdare, education, training anddevelopment are seen as a foundation for economic productivity and as crucial tools to build empoweredand dedicated employees. In this regard, the company actively promotes and follows a number ofeducation programmes, including adult education, apprentices, trainees, learnerships and formaleducation assistance.
Aberdare Cables has always been an active supporter and pillar of strength for the communities in which itoperates.The company is championing a number of social investment initiatives across our country.Thebiggest of these investments has been the continuous sponsorship of Sinethemba home for streetchildren in Port Elizabeth.
As a proudly South African company, Aberdare participated actively in the development of the ICT charterand the draft DTI BBBEE codes. Aberdare will continue to adopt a proactive approach to effect thetransformation that the codes specify and to lead the cable industry in this regard. We enjoy a BBBEEstatus of Level 3.

ContentsPaper Insulated Cables
Paper insulated cables have been in use longer than any other type of cable insulation and, dueto the reputation built up over the years, are still today a great favourite with engineers. Whenproperly selected and correctly installed, this product can be relied upon to provide asatisfactoryand trouble-free performance formany years.
Aberdare Cables started making paper insulated cables in SouthAfrica in 1948. Our associationwith one of Europe’s largest and oldest cable manufacturers placed at our disposal the technicalexpertise and research facilities which paved the way for an intensive expansion programmewhichstill continues today.
Application
Paper insulated lead covered cables can be used in many electrical distribution and reticulationapplications. Special constructions are also available for use in specialised applicationsincluding:-
• Electrical distribution in the petrochemical industry.
• Mining - a special construction for shaft installation is available with water blocking aswell as flame retardancy.
• Fire and explosion hazardous areas.
• Submarine cables.
OverviewPaper Insulated Cables
1
Paper insulated cable manufacture is carried out in accordance with SANS 97. The paperinsulation is made up of layers of long-fibred paper tapes made from high-grade wood-pulp, thetexture and quality of which have been carefully controlled to ensure no imperfections. Thesepaper tapes are lapped helically around the conductors to form a complete compact andsmooth covering, with the radial thickness required according to the voltage of the cable. Theouter layer is generally numbered to enable positive core identification. (The laid-up cores arebound with further layers of helically applied paper tapes for belted-type cables, or copperwoven tapes for screened cable.)
As paper itself is a hygroscopic, fibrous material, its electrical properties are rather poor. Ittherefore requires to be dried thoroughly under vacuum and impregnated with a stableelectrical grade non-draining compound. This non-draining compound has a drop point ofgreater than 80°C which means that the impregnant does not migrate under normaloperating conditions, or when installed on gradients.
To protect the impregnated paper insulation from contact with water during its intended life,an extruded seamless sheath of lead or lead alloy is applied by means of a lead extruder.(Ductibility and durability are essential features of the sheathing.) Although ductile, purelead is liable to fail by cracking when exposed to mechanical vibration such as may occur onbridge crossings or near railway tracks, and in these circumstances lead alloy ‘E’ is preferred.This has a considerably higher tensile strength than pure lead, particularly under alternativemechanical stress.
As the lead sheath requires protection, a bedding of bitumen-impregnated paper and fibrousmaterial or an extruded plastic layer is applied to prevent the lead from being deformed bythe armouring. An armouring of steel wire or double steel tape is then applied to give thecable full mechanical protection.
The final stage calls for an outer serving of bitumised fibrous material applied over thearmour. An ex-truded plastic serving may also be used. The paper insulated cable is nowcomplete and moves to the testing stage.
The SANS specification allows for heavy duty cables which are generally used in mines orother onerous conditions. Such cables are manufactured with thicker insulations, leadsheaths, armouring and sheathing.

Aberdare cables provides a comprehensive backup service for our products including:-
• Technical seminars throughout the country.• Technical support on all aspects of cable and accessory selection.• Training schools for jointing and terminating.• Cable design service.• Supervision of cable installation and commissioning.
QualityAssurance, Quality Control andTesting
As electric power cables are manufactured to provide many years of service, it isnecessary that the raw materials used are of the highest quality and conform to the rigidspecifications laid down by South African Bureau of Standards. This also means that theproduction process has to be carefully controlled, particularly in areas where heating,drying or cooling cycles can be critical to the overall characteristics and electrical propertiesof the cable. Chemical, physical and electrical tests are carried out at various stages ofmanufacture. Final tests are all in accordance with SANS 97. Quality assurance systems arein compliance with SABS ISO 9000 series.

1. All data is approximate or nominal.
2. Dimensions are to SANS 97.
3. Drums sizes : Dimensions for steel wire armoured cables have been used for calculationof drum sizes. Drums for double steel tape armoured cables will be slightly smaller andcables with PVC sheaths will have marginally larger drums.
4. Despatch masses includes drum lagging.
5. For sustained current ratings, the latest version of SANS 10198: "The selection, handlingand installation of electric power cables of rating not exceeding 33 kV" must be consultedwhere applicable.
6. Supplementary Notes
Relative values of mass and capacitance of drained cables will be marginally less than thoseindicated in the relevant tables which follow.
C = equivalent star capacitance of each core to neutral= 1,2 C approx (Capacitance varies according to relative permitivity and geometry)
C = approximate capacitance of one core, the others earthed to lead sheath. C isthe normal test value

Derating FactorsFor Installation Conditions other than Standard
25
Cables may be grouped in air without derating provided that:
1. Horizontal formation:
2. Vertical formation:
i) The clearance is not less than 6 times the overall diameter of the cable or 150 mm,whichever is the least.
i) The clearance from a supporting wall is not less than 20 mm, and;ii) The vertical clearance between cables is not less than 150 mm, and;iii) If the number of cables exceeds four they are installed in a horizontal plane.
Short Circuit Ratings of Cables
Short circuit conditions do not lend themselves readily to rigid treatment. The variables areknown but their interaction is extremely complex. In the case of armoured, lead sheathedcables with conductors greater than 240 mm² in particular, earth fault currents may increasethe lead sheath temperatures to above tolerable limits. An absolute sheath temperature of170°C (below the melting point of jointing metal) should not be exceeded. The maximumpermissible conductor temperature is 160°C for conductors with soldered lugs and ferrulesand 250°C for conductors with crimped or welded lugs and ferrules. In calculating the factorsfor short circuit ratings given for guidance in the table below, it was assumed that symmetrical3 phase short circuit currents occur under full load conditions, and that adiabatic conditionsprevail, i.e. no heat is lost from the conductors during the fault conditions.
Note
Example
For times other than 1 second, divide the calcultated 1 second short circuit current rating by the squareroot of the actual time in seconds for which the short circuit rating is required.
120 mm², 11 kV screened 3 core copper conductor cable with soldered ferrules or lugs(maximum permissible conductor temperature = 160°C).Temp. of conductors at inception of short circuit = 70°C1 second short circuit current rating = 120 mm² x 0,115 kA/mm²
= 13,80 kA2 second short circuit current rating = 13,80 kA
= 9,76 kA2

Lead Sheathed Cables Subject toVibration
Corrosion of Lead Sheaths
Vertical Installations
Lead sheathed cables to be installed in positions subject to moderate vibration, viz. bridges,tunnels, factories, mine shafts etc, should have sheaths of Lead alloy E, and should preferablybe armoured.
Some installation conditions may be aggressive to lead sheaths which are protected only withconventional bitumen impregnated textile bedding and / or serving. This condition may occurin soils that are otherwise relatively inert. Heavy sporadic rain in a predominately dry areatends to accumulate in the disturbed terrain of a cable trench. Subsequent evaporationconcentrates any dissolved salts and organic compounds, which together with differentialaeration in contact with lead sheath, can supply the electrolyte and cause a galvanic corrosionof the lead. Presence of earth currents arising from local arc furnaces or DC traction mayfurther complicate the process of corrosion.
When this condition is known to exist, as may be evidenced by relatively frequent replacementof metal water pipes in the area, it is recommended that the conventional bedding and / orserving be replaced by an extruded PVC sheath which is fully protective for most conditions ofinstallation. Graphite coated PVC sheaths are available when it is intended to carry out regular(bi-annual) sheath integrity tests on the installed cables. When such graphite coated PVCsheathed cables are tested the leakage current flowing through the sheath during theapplication of 10 kV DC for one minute shall be typically less than 5 mA/km.

The problem of drainage of impregnant from fully impregnated cables installed vertically or onsteep gradients has been significantly reduced by the use of non-draining compounds. Non-draining impregnants are designed to remain solid at normal operating temperatures.Nevertheless, cables so installed which are likely to be subjected to repeated overloads, arerecommended to be of the drained type. In this design a full impregnating cycle is appliedwhich consists of a period of drying under heat and vacuum followed by full impregnationunder heat and pressure. Before exposing the cable to the atmosphere, the surplusimpregnant is withdrawn during a further period of heat and vacuum.
InstallationPaper Insulated Cables
27
A drained type cable may be subjected to short circuit conditions, resulting in a maximumconductors temperature of 160°C without significant downward movement of the dielectric.Extra dielectric thickness is applied to minimize the dielectric stress in the drained installation.
The drum of cable should be properly mounted on cable jacks or a cable trailer with asupport bar of adequate strength relative to the drum width and mass and also to thedistance between the bar supports. Collars must be worn to avoid axial creeping of thedrum during drum rotation. If the inside end of the cable is protected by a metalcovering, this and any securing ties must be removed before paying off the cable. Thedrum should not be allowed to overwind during withdrawal of the cable, sincedangerous kinks may be formed and the creation of loose convolutions may cause theinner end to creep out of the cable drum hole.This creep must be allowed to take place.
Cable bending should be done slowly and carefully, and precautions mentioned in (a)above should be followed when applicable. Electric cables should not be bent to radiiless than those derived from the table below.
Installation of Cables
a) Low Ambient Temperatures
b) Handling of Drums
c) Minimum Bending Radii
Unless precautions have been taken to heat the cables above 10°C for at least 24 hoursprior to installation, cables should not be installed at temperatures lower than this. Inthe field this may be achieved by the judicious use of heaters around the cable drumsunder a tarpaulin shield.

Handling and Installation of Cables
Transfer of Drums of Cable
Shaft Cables
Refer to SANS 10198“The selection, handling and installation of electric power cables of ratingnot exceeding 33 kV". In particular, care must be taken in handling and transporting cables,since damage may seriously impair subsequent cable performance and life.
Under no circumstances should a drum of cable be dropped during transport to or unloadingon site. Rolling of a drum of cable must always be in the direction of the arrow marked on theflange, otherwise loose convolutions of the cable develop, which may result in damage to thecable during subsequent pay off.
Shaft cables are often exposed to extreme conditions, being installed vertically, exposed tomoist corrosive atmosphere, and susceptible to mechanical abuse. In order to enhance thecables performance under these conditions, special design measures are taken, theseinclude:
1. Process changes to ensure impregnating compound cannot migrate. This provides thecable with improved drainage performance at operating temperature.
2. Employing a fully waterblocked, helically applied, galvanised steel wire armour layerover the lead. This provides mechanical protection against damage caused by rockfallsand the vibration caused by air buffeting from high speed skips passing in closeproximity to the cables. A suitable water blocking compound encapsulates these wiresto retard corrosion and stop free water being piped to joints, terminations or anciliaryelectrical equipment.
3. The whole cable is sheathed in a flame retardant, low halogen PVC sheath. This acts asan initial fire and mechanical barrier.
