Copperweld is often used in substation 'ground grids'. This interview with R-Delta proves 50+ year subgrade performance in Texas without corrosion.
Copper is at a ten-year high right now (2021). When it gets stolen, the cost to an electric utility is about 100x the recycle value that the thief pockets!
Copperweld gives a 17% resiliency improvement over copper in grounding applications! Why? Four reasons: theft, loosening, corrosion, and breaks.
For critical applications, engineers work with Copperweld to select the right steel core: mild, high strength, or extra high strength steel!
Thieves have noticed the rising price of copper, too. Prevent $60 million in losses! Copperweld solves the risk of grounding wire theft.
Copperweld brand wire is 40% stronger than copper, or more! Higher strength means it's more reliable and can harden your grid against threats.
ASTM B910 is the construction standard for CCS. This weld-quality check is performed on every batch of genuine Copperweld CCS.
Trickle current can be important in overloaded grounding circuits that act as 'neutrals'. So, we verified our continuous current ratings.
By simulating short circuit fault currents at the world's best high power test labs, our engineering team has discovered the true limit of Copperweld grounding solutions. The results were surprising.
Did you know that the fuse rating for Copper (Cu) is significantly less than the IEEE values that engineers expect and use in their calculations?

In this video series, Copperweld’s Jeff Jordan explores trends, technologies, and challenges to conventional thinking in the field of high voltage grounding conductor selection.
This article introduces a method for quantifying the reliability of grounding conductors for the design of substations and other high voltage electrical applications.
This paper presents empirical evidence spanning several decades that questions the conventional short circuit performance calculations used to select copper-clad steel (CCS) conductors.
