Application
It is used to transmit and distribute power on the power line of A.C rated voltage 0.6/1kV. The flame-retardant power cable is suitable for environment with demand on flame-retardant performance. Fire-resistance power cable is used in the environment with high demand on fire-resisting performance such as high-rise building, the big market;

Using feature & Main Technical Performance：
1.The Max. long-term operating temperature of conductor isno more than 70 .Flame-retardant 105 PVC insulation no more than 105 .
In short-circult (The Max. long-term is continue no more than 5 second) . The highest temperature of conductor is no more than 160 . (105 cable PVC insulation no more than 205 ).
2.Environment temperature should be no lower than 0 .The min bending radius should be no smaller than 15 times of cable outer diameter.
3.D.C Conductor risistance complies with the stipulations of GB/T3956 in 20 .

4.Working frequency Voltage Test:3.5kV/5min with out puncture.
5.Flame-retardant character:
Flame-retardant cable could endure firing test in bundle stipu lated in GB/T18380.3(IEC60332-3:1997).
Low smoke low halogen flame-retardant cable could endure firing test in bundle stipulated in GB/T18380.3(IEC60332-3: 1997), and smoke density in firing should comply with stipulations of T17651.2-1998(IEC61034-2:1997).HCL content of gas separated out in firing should be no more than 100mg/g. and comply
with GBT17650.1-1998(IEC60754-1:1994).
Fire-resistance cable could endure fire rating test in GB/ T19216.21-2003(IEC60331-21:1999)
