Copper Clad Steel Wire

Copperweld is for use as earth conductor for overhead transmission and distribution lines (OHTL) of electric power. The unique structure of copper clad steel wires provides perfect grounding solution of high strength, good electrical conductivity and property of corrosion-resistant. It is a good replacement for alumoweld and galvanized steel guy wires.

ACSS Conductor Aluminum Conductor Steel Supported

ACSS is used for overhead distribution and transmission lines. It is designed to operate continuously at elevated temperatures up to 250°C without loss of strength. It sags less than a comparable ACSR under electrical loading; it is self-damping if pre-stretched during installation; and its final sags are not affected by long term creep of aluminum. […]
