Product feature and purpose:
Cross-linked polyethylene insulated power cables is characterized with high mechanical strength,strong resistance to environmental stress,excellent electrical properties ,powerful resistance to
chemical attack.In addition,the light and simple products are user-friendly.This product is suitable and designed for power transmission and distribution system of rated voltage 0.6/1kv.In terms
of the main feature of anti-flaming cable,the cable is not liable to ignite or continued ignition is only limited to a certain scope applicable to power station ,subway ,tunnel ,high-rise building,large
industrial and mining enterprise,oil field,coal mine and other places of intensive distributed electric cables. Operative standard:
GB/T 12706,IEC 60502 and relevant domestic and international standard.For example,BS,VDE,JIS,AEIC,and so on.
Operational performance:
The maximum allowable operating temperature of the cable conductor:90 C in normal condition and 250 C in case of short circuit (maximum duration of short circuit is 5s).
