0.6/1kV Cross-Linked Polyethylene Insulated
(Flame Retarding) Power Cable
Uses:
The product is suitable to be used for electrical distribution and supply of transmission line with power frequency of rated voltage 0.6/1kV or less. And 900C is the allowable highest long-term operating temperature of cable conductor; the highest temperature of cable conductor can't be above 2500C when short circuit occurs.

Flame retarding cable can be manufactured following the Standard GB/T18380.3-2001 (same effect with that of IEC60332) according to the requirements of users. The relative specifications are divided into Category-A, B and C, and the designations of “ZRA-”, “ZRB-” and “ZR(C )-” can be added in the front of the original model number of cables.
Halogen-free and low-fume cables also can be manufactured following both of the GB/T17650-1998 (same effect as IEC60332) and GB/T17651-1998 (same effect as IEC601034, and the designation of “WDZ” can be added in the front of the original model number of cable.
