Eliminating the Cost of Upsizing

In substation grounding design, engineers often increase conductor size to provide an additional margin of mechanical strength.

While effective, this practice also increases material costs across the entire grounding grid—even when additional electrical capacity isn't required.

ArcAngel changes that equation. Because its Copper-Clad Steel construction provides substantially greater mechanical strength than electrically equivalent copper conductors, engineers can select conductors based primarily on electrical requirements without adding unnecessary material simply to improve durability. The result is a grounding conductor engineered to deliver both electrical performance and exceptional mechanical resilience within a single optimized design.

For utilities, consulting engineers, and EPC contractors, this approach creates opportunities to optimize grounding system design while helping control project costs. Rather than relying on additional conductor size to achieve greater strength, ArcAngel builds that strength directly into the conductor itself.

Laboratory testing had validated the design in open air. One final question remained: How would ArcAngel perform under conditions that more closely resemble an actual buried substation grounding grid?
