Fire-resistant power cable

[Introduction]:
It is used in the environment with high demand on fire-resisting performance such as high-rise buildings, oil field, power station, power plant, mine, chemical industry and subway. It is also the necessary cable prepared for emergency power, fire pump and communication system of elevator.
[Working conditions]:
1. A.C. rated voltage (U0/U): 0.6/1KV
2. Max. Working temperature in long term
1. Flame-retardant PVC insulation & sheath: 105℃ XLPE insulation: 90℃
2.Fluoroplastics insulation & sheath: 200℃ & 260℃; Fluoroplastics insulation & 105℃ flame-retardant PVC sheath 90℃ & 125℃
3. Without halogen & low smoke, flame-retardant polyolefin insulation & sheath: 90℃ & 125℃
3. Min. environment temperature:
1. Flame-retardant PVC sheath: -40℃for fixed installation and -15℃for non-fixed instillation.
2. Fluoroplastics insulation & sheath: -60℃for fixed installation and -20℃for non-fixed instillation
4. Environment temperature for cable installation should be no lower than 0℃
5. Fire-resistant character: as stipulation in IEC331 and GB12666.6.
