Copperweld is a bimetallic manufacturer specializing in power and grounding conductors for building construction, power grid, utilities, communications and transportation. For over 100 years, it has been our mission to make the most reliable and innovative wires on the market.
Copperweld’s metallurgical expertise and value-engineering approach have produced bimetallic products that revolutionized industries. Our world-wide network of facilities manufacture bimetallic power and grounding conductors originating in Copperweld’s facilities in the heart of the mid-south, USA.
The culture of excellence and innovation that inspired Copperweld’s first products over 100 years ago still drives us today. Our team of engineers is always looking for better ways to test, manufacture, optimize, customize, and support the products we deliver. We’re Wired to Protect.
Electrical conductors with all of copper’s best qualities (and more)
Copperweld® Building Wire is a Cu-Clad electrical conductor designed to meet and exceed copper standards. Designed with safety and longevity in mind, Copperweld® meets both ASTM and UL standards, and its lab performance exceeds its ratings in Code. With 8% more energy efficiency, it also runs cooler and reduces energy costs.
Copperweld's bimetallic bond reduces theft incentives.
When installed per NEC, CCA is the most energy-efficient conductor.
NEC Code-Compliant for 600 Volt branch circuit conductors.
Protecting the Power Grid for better safety and reduced downtime
Copperweld wire is 17% more reliable than standard copper wire. This reliability improvement takes into consideration the likelihood of wire breaks, loosening joints, theft, and wind fatigue after installation. There’s a reason why you’ll find Copperweld wires in the field that are still ASTM spec-compliant after 50+ years of service.
Protect yourself against a missing or broken ground.
Trust a conductor that’s more likely to be there when you need it.
Engineered to protect your PV equipment and your bottom line.
Higher mechanical strength and 10% lighter in a smaller bundle size
Optimize your vehicle’s power and signal distribution system for reduced weight, increased mechanical strength, and smaller bundle diameters. Copperweld’s proprietary Copper Clad Steel (CCS) and Copper Clad Aluminum (CCA) wires make it the ideal solution for Primary Wire, Battery Cables and High-Voltage Cables in weight-conscious applications.
Data, signal (CCS) and power (CCA) wiring with lower weight and material cost than copper
Handles and connects like copper, while reducing weight and bundle size
Switch to traditional connection systems versus welding for lower weight and lower cost
Cost-saving copper alternative for communications and mining cable
Copperweld® Signal Wire’s annealed, high-carbon steel core provides superior impact resiliency with two times the tensile break-load strength of commodity copper. Its ability to stretch more than 15% allows it to accommodate ground movement, making it perfectly suited for underground construction and trench deployment applications.
Open-trench, integrated fiber and Innerduct wire offering superior strength and corrosion-resistance
CCS for better strength, flexibility and elongation in down-hole detonator applications
CCS and CCA coaxial cores offer unmatched cost performance and durability
