162-23-7080 250 MCM 1C 37Strand Aluminum Shield 1/3 Neutral 133% EPR Concentric BC PE Okoguard URO-J 35KV URD Cable

Allowable Ampacity for 162-23-7080 250 MCM 1C 37Strand Aluminum Shield 1/3 Neutral 133% EPR Concentric BC PE Okoguard URO-J 35KV URD Cable:100 Amps

About:

The cable is a high-voltage, single conductor (1C), aluminum shielded cable designed for utility distribution applications. It features a 1/3 neutral, 133% Ethylene Propylene Rubber (EPR) insulation, concentric Bare Copper (BC) shielding, and a Polyethylene (PE) Okoguard jacket. This cable is rated for 35KV Underground Residential Distribution (URD) systems.
