Aluminum Clad Steel Wire

Aluminum Clad Steel is used as an overhead ground wire, shield wire protecting transmission lines against lightning damage, and in other applications within the power utilities and formed wire industries. It is also used in optical ground wire (OPGW) systems, providing both mechanical support and electrical conductivity.

● Conductor Type: Concentric-stranded conductors made from round aluminum clad steel core wires.

● Stranding: Galvanized steel wires are stranded concentrically, with the outermost layer being laid right-handed and the subsequent layers having the opposite direction of lay.

● King Wire:  A conductor may incorporate a larger central wire (king wire) if necessary. This wire's diameter is typically 5% larger than the surrounding wires and is based on conductor design requirements.
