450/750V Electric Wire is used for lighting, electronic equipment, instument and communication equipment with rated voltage 450/750V
Specification: 1. The rated voltage of the electric wire should equal to or higher then the rated voltage of the system when electrical wire are used at AC system. If the wires are used at DC system, the rated voltage of system should lower then 1.5 times as high as rated voltage of cable and wires. The working voltage of the system could be 1.1 times as high as the rated voltage of the cable.
2. The long term working temperature should lower then 70oC. The working temperature of BV-90 should lower then 90°C. And the laying temperature should higher then 0°C.
