| Alumoweld® & Copperweld: Aluminum-Clad Steel Wire & Strand |
|
| Alumoweld® 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. |

Overhead Ground Wire
Modern high-voltage transmission lines utilize an overhead ground wire for protection against interruptions due to lightning. The high strength and low weight of Alumoweld strand permit it to be strung with sags that provide maximum mid-span clearances above power conductors to insure proper insulation coordination. The thick aluminum cladding on each wire offers optimum protection against atmospheric corrosion while providing the conductance important in the proper operation of protective relays. The high conductivity of Alumoweld strand also reduces the temperature rise of the static wire under fault conditions.
Type M® Guy Strand
Alumoweld Type M Guy Strand is an economical, non-corrosive guying material for use on transmission and distributions lines. The thick cladding of aluminum on each wire protects the high strength steel core from rusting and subsequent loss of strength. Costly maintenance resulting from corrosion is eliminated, and the original safety factor of the guy is maintained throughout the life of the line. For guying power lines, telephone lines, railway signal and communications lines, towers, masts, stacks and similar structures, Alumoweld Type M guy strand is both practical and economical.
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 aluminum 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.
