ALUMINUM CLAD STEEL WIRE/STRAND

More durable than other options in corrosive environments, resulting in lower maintenance and replacement costs

Lighter than steel strands of the same size, when used for overhead ground wires, larger span lengths, less sag, and heavier loads can be achieved, thereby reducing the tension on the tower or support structure and the tower The frame stress is reduced accordingly.

Excellent conductivity: 14-40% for aluminum clad steel wire
