141-23-7031 4/0 AWG 1C Bare Copper Unshielded EPR Concentric Full Neutral Okolene 35KV 420 Okoguard URO-J Cable

Allowable Ampacity for 141-23-7031 4/0 AWG 1C Bare Copper Unshielded EPR Concentric Full Neutral Okolene 35KV 420 Okoguard URO-J Cable:100 Amps

About:

This cable is constructed with a single conductor of  4/0 AWG  bare copper, which is unshielded and insulated with Ethylene Propylene Rubber (EPR). The "concentric full neutral" design means that neutral wires completely encircle the insulated conductor, enhancing the cable's electrical balance and fault performance. The Okolene layer, designated here as "15KV 175," likely refers to its high voltage rating and thickness. The Okoguard URO-J is an outer jacket made from a unique compound designed for enhanced durability and protection against environmental factors.
