Description

Purpose:
This product is mainly used for 0.6/1kv power transmission and distribution. When flame retardant is required, flame retardant model can be selected. The fire-resistant type can be used in high-rise buildings, large shopping malls and other high-density areas that need fire-fighting and life-saving.

Executive standard:
This product is in accordance with GB 12706 1、GB12706. 2. Design and manufacture.
Flame retardant PVC insulated power cables and fire-resistant PVC insulated power cables are manufactured according to the enterprise standards, among which the flame retardant specially conforms to GB 12666 5 (iec332-3) and fire resistance characteristics of composite GB 12666.6 (iec331).
