0.6/1kV PVC Insulated & PVC Sheathed
(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 3.6/6kV or less. And 700C is the allowable highest long-term operating temperature of cable conductor; the highest temperature of cable conductor can't be above 1600C when short circuit occurs.
