Copperweld + Copper Conductors
Copperweld + Copper Conductors, composed of both solid copper and extra high-strength copper-cover steel, are used for overhead power distribution lines where extra strength is required. For example, it may be used in rural farmland where ice is expected to accumulate on the line or for economical reasons with long-span installation. Our most popular configuration, Type-A—made of two copper wires and one Copperweld wire—is stranded into a triangular shape to minimize line vibration in the wind.
Efficient Spans
Copperweld powers rural America. The rugged design of Copperweld's traditional Type A stranded conductors permit dependable, low-cost electric service. Installed throughout the US since WWII, the high strength of Copperweld-Copper Conductors (CCC) means fewer poles per mile, fewer insulators, less hardware, and lower labor costs.
Non-rusting Protection
Corrosion-resisting copper forms the exterior of each Copperweld power conductor, assuring long life. For critical applications, engineers depend on Copperweld's rust-resistant track record of successful installations throughout the power grid. Copperweld Century Grid products have been protecting the power grid for over 100 years.
Easy to Replace
Industry-standard bronze connectors for copper wires and cables also fit Copperweld. Customers have been relying on Copperweld power lines for decades. In many cases, it is much less expensive to repair existing lines than to replace them. New wire can be spliced into existing lines as the bimetal core ensures a tight connection for years to come.
