Alumoweld Wire and StrandAlumoweld wire consists of a thick cladding of pure aluminum over a high-strength steel core. Alumoweld wire offers the advantages of each metal. It is ideal for overhead ground wire, neutral messengers, line wire and guy strand. Alumoweld wire and strand is used by power utilities, as well as formed wire and optical ground wire manufacturers. Alumoweld outlasts other options by as much as 200% in corrosive environments, significantly lowering maintenance and replacement costs. When compared to solid aluminum wire, Alumoweld offers tremendous savings.
featuresThick Aluminum CoveringAlumoweld wire is produced with the concentric aluminum covering comprising 25% of the cross-sectional area, with the aluminum thickness 10% of the wire radius. The high proportion of aluminum offers an excellent degree of electrical conductivity and permanently protects the high strength steel core.
High ConductivityCompared to solid aluminum wire of the same diameter, Alumoweld wire has a direct current conductance of 33%. It has about three times the conductivity of galvanized steel wire. For high frequency currents where skin effect is a factor, the conductivity of Alumoweld wire approaches 100% of solid aluminum. When Alumoweld wires are combined with aluminum wires in composite conductors, a wide range of strength and conductivity characteristics is possible.
Corrosion ResistanceThe thick aluminum cladding of Alumoweld wire provides a high degree of corrosion resistance, resulting in longer service life and reduced maintenance. Accelerated laboratory tests exposing Alumoweld wire to various types of corrosive conditions have proven that Alumoweld wires have corrosion resistance comparable to EC grade aluminum. The condi-tions simulated in the test included industrial, marine and tropical.
Combines High Strength with Low WeightAlumoweld wire has a higher strength-to-weight ratio than any other wire commonly used on overhead lines. Size for size, it has about the same tensile strength as extra high strength steel wire, but weighs approximately 15% less. It has eight times the strength of solid aluminum wire of the same diameter and only a little more than twice the weight. This high strength-to-weight ratio provides a maximum margin of safety for long-span construction. The strength of Alumowelds steel core is protected by the thick aluminum covering.
how is Alumoweld made?The Alumoweld process consists of a continuous application of pure atomized aluminum powder to a high strength steel rod. Proper control of head and pressure refines the cladding and develops a controlled atomic weld. The resulting bimetallic rod is then cold drawn into finished wire sizes without changing original proportions of aluminum and steel.

Alumoweld Overhead Ground WireAlumoweld wire and strand is used by power utilities, as well as formed wire and optical ground wire manufacturers. Alumoweld outlasts other options by as much as 200% in corrosive environments, significantly lowering maintenance and replacement costs. When compared to solid aluminum wire, Alumoweld offers tremendous savings.
featuresCorrosion ResistanceAlumoweld overhead ground wire has excellent corrosion resistance. Its strength and con-ductivity remain unchanged in any atmosphere where aluminum is satisfactory, especially those known to be corrosive from industrial or atmospheric conditions.
This assurance against corrosion is obtained through the application of a thick covering of pure aluminum, which provides a substantial barrier of protective metal. The minimum clad-ding thickness of Alumoweld is 10% of the radius of the wire. The cladding has a continu-ous, strong metallic bond to the steel core that will not crack or flake.
Strength Comparable to SteelAlumoweld also provides strength greater than or equal to other overhead ground wires. For commonly used wire sizes, the tensile strength of the individual wire can approach 200,000 pounds per square inch. When used in a strand for overhead ground wire, this high strength permits greater span lengths, less sag, and heavier loads under storm loading conditions.
LightweightDirectly related to strength and sag performance is the lighter weight of Alumoweld. Due to its thick cladding of aluminum, Alumoweld is 15% lighter than a steel strand of equivalent size. This lighter weight, combined with high strength, permits Alumoweld to be installed to the same sags as steel with correspondingly lower tensions and lower stresses on the tow-ers or supporting structures.

Alumoweld Type M Guy Strand
featuresCorrosion ResistanceAlumoweld Type M guy strand is an economical, corrosion resistant guying material for use on overhead line structures. The thick cladding of aluminum on each wire protects the high-strength steel core from rusting and subsequent loss of strength. Costly maintenance is eliminated, and the original safety factor of the guy is maintained throughout the life of the line.
Thick Aluminum CladdingThe Alumoweld wire used to make Type M guy strand is unique in that the aluminum clad-ding thickness is guaranteed to be no less than 10% of the wire radius. Thus, a thick corro-sion barrier, that is pure aluminum not zinc or an iron-aluminum alloy, protects the steel core.
Another important feature of any coated or clad wire is the bond between the coating mate-rial and the base metal. In the case of Alumoweld wire, the aluminum cladding and steel core are joined by a continuous ductile weld. This assures against cracking or separation of the protective aluminum from the steel core.
Lightweight and ConvenientAlumoweld Type M guy strand is easily handled and installed. It weighs less than any of the other high-strength guying materials.

Alumoweld Aluminum Conductors (AWAC)AWAC combines Alumoweld with 1350-H19 aluminum wire to provide the electric industry a new versatility for distribution line construction. The combination of high conductivity alumi-num with high strength Alumoweld wire, in varying proportions, allows the designer flexibility for solving new designs or reconductoring. AWAC offers unsurpassed strength-to-weight ratio. Aluminum equivalents of No. 4 AWG through 4/0 AWG each offer a complete range of breaking strengths. In addition to its use as a phase conductor, AWAC is well suited for other electrical-mechanical applications on distribution and transmission lines.
featuresDesigned for VersatilityAWAC is a reinforced aluminum conductor of improved design. Alumoweld wires perform the dual function of providing strength and conductance. AWAC offers both lightweight and high strength for any given AWG conductivity. To make AWAC a more versatile conductor, the ratio of Alumoweld to aluminum wires has been varied to provide the largest range of breaking strengths offered by any conductor.
Corrosion ResistanceThe steel core of each Alumoweld wire is protected against rust by a thick covering of aluminum. This provides the same corrosion resistance as AWACs solid EC aluminum wires. Thus, Alumoweld is safely used in any strand position of an AWAC conductor. This design advantage allows conductor configurations of high strength without sacrificing conductivity or corrosion resistance.
Unsurpassed Strength-to-Weight RatioAWACs Alumoweld wires act as the strength members of the conductor while the aluminum wires reduce the overall weight. This combination results in a high strength-to-weight con-ductor. When more than one Alumoweld wire is used, the AWAC conductors are unmatched by any other conductor in strength-to-weight ratio. For example, the 5/2 AWAC has approxi-mately 50% more strength and only weighs 20% more than a 6/1 stranded ACSR conductor.
