ArcAngel®

Flexible Copper-Clad Steel (CCS) conductor for demanding utility applications

Designed for long-term performance

Century is engineered for unmatched durability, long service life, and dependable grounding in the toughest utility environments.

Century delivers high-strength grounding performance for utilities that prioritize durability in the harshest conditions. Designed to resist mechanical damage, deformation, and long-term environmental exposure, Century supports dependable grounding across substations, transmission corridors, and remote infrastructure. With Bare, Camo, and Hide finish options, utilities can match physical visibility and site needs.

Features and Benefits:

Unmatched Durability – Engineered for maximum mechanical durability, Century withstands demanding installs where resiliency is essential.
Superior Strength – With the strength of steel, CCS resists stretching, breakage, and deformation under mechanical and thermal stress.
Reduced Theft Incentives – With a rugged steel core and lower scrap value than solid copper, CCS helps reduce theft incentives in remote or unmonitored locations.
Corrosion Resistance – Copperweld CCS conductors are engineered to perform in demanding above-grade and below-grade grounding applications.*
Bare, Camo, or Hide Finishes – Available in multiple finish options, Century helps utilities match site visibility needs and installation environments.
*
Service life varies based on soil conditions, installation environment, and exposure factors. Underground performance may be impacted by soil chemistry, pH, moisture, and circulating currents. These conditions influence the performance of all grounding conductor materials, including copper and CCS.
