Copperweld® Century Grid™
Legendary strength and superior performance — ensuring the reliability of the power grid for over 100 years.
How do you build a 100-year power grid?
Start by updating to a conductor that offers the durability to deliver a century of service. Copperweld® Century Grid products offer the best of both worlds: the strength of steel + the conductivity of copper. The end result is a conductor that offers the same performance as copper but lasts 2x longer.
Copperweld grounding solutions have been used in the power grid since 1915, because the unused middle of a copper conductor is a great place to add strength, improve survivability and increase service life — a process known as 'Hardening the Grid'.
17% More Reliable
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. From rural farms in Nebraska to substations in Kentucky, there's a reason why you'll find Copperweld wires in the field that are still ASTM spec-compliant after 50+ years of service.
Industry-standard bronze connectors for copper wire and cable will also fit Copperweld, too. Mechanical and crimped connectors are made to fit a range of diameters and can often be used for the equivalent Copperweld solution. Off-the-shelf lugs and exothermic connectors are available from a number of suppliers. And, Copperweld's bimetal core ensures a tight connection for years.
Hardening the Grid
Hardening your power grid against the spread of outages can be as simple as selecting the right conductor. For the applications that matter most — critical applications that call for more reliability than usual —engineers select components with a track record for standing the test of time. Copperweld Century Grid products have been protecting the Power Grid for over 100 years.
