1. The rated voltage of the wires should equal to or higher then the rated voltage of the system when wires 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 70 oC. The working temperature of BV-90 should lower then 90 oC. And the laying temperature should higher then 0oC.
3. The curve diameter of the wire should longer than 8 times of the diameter of the outer diameter of cable and wires if their outer diameter is 25 mm or above. If the diameter of cable and wires is above 25 mm, the curve diameter should be at least 12 times of the outer diameter of the cable and wires.
