Wire and Cable
Refractory cable

This product is suitable for high-rise buildings, oil fields, power stations, power plants, mines, chemicals, mines, subways and other places where high fire protection [1] is required. It is also a cable for emergency power supplies, fire pumps, and elevator communication signal systems; This product has the fire resistance ability of flame retardant refractory cable. Under the condition of direct flame burning, there will be no short circuit and open circuit failure within a certain period of time (not less than 3h). Ensure that the power supply is continued to maintain the lighting and transmission signals, and to protect the staff with sufficient time. Evacuate safely and facilitate fire suppression and reduce losses.

Conditions of use 1. AC rated voltage: U. / U (V series: 600 / 1000V, K series: 450 / 750V, B series: 450 / 750V).
2. The maximum long-term working temperature of the cable (1), olefin-resistant polyfluoroethylene insulation and sheath: 70 ° C and 105 ° C; XLPE insulation: 90 ° C;
(2) Fluoroplastic insulation and sheath: 220 ° C and 260 ° C; Fluoroplastic insulation and 105 ° C flame retardant PVC sheath: 90 ° C and 125 ° C.
(3) Low-halogen low-smoke flame-retardant PVC insulation and sheath: 70 ° C; Halogen-free low-smoke flame-retardant polyolefin insulation and sheath: 90 ° C and 125 ° C.
3. Minimum ambient temperature:
(1) Flame-retardant PVC insulation and sheath: fixed laying -40 ° C; non-fixed laying -15 ° C;
(2) Fluoroplastic insulation and sheath: fixed laying -60 ℃; non-fixed laying -20 ℃;
4. The safe laying temperature of the cable should not be lower than 0 ℃.
