Allowable Ampacity for 161-23-3084 250 MCM 1C 37Strand Aluminum Shield Full Neutral 133% EPR Concentric BC PE Okoguard URO-J 15KV URD Cable:100 Amps

About:

The single-conductor underground residential distribution (URD) cable, designed for primary distribution systems operating at 15kV. This cable features a solid aluminum conductor, an aluminum shield, and a full concentric neutral. It is insulated with Ethylene Propylene Rubber (EPR) rated at 133%, and protected with a Polyethylene (PE) jacket. It is suitable for direct burial or duct installations and is designed to meet stringent safety and reliability standards.
