1. The rated voltage of the wire should equal to or higher than 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 be lower than 1.5 times as high as rated voltage of cable and wire.
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 of electric wire should be less than 70 degree.
And the long term working temperature of RV-90 electric wire should be less than 90 degree.
And the laying temperature should be higher than 0 degree.
3. The curve diameter of the wire should be longer than 8 times of the diameter of the outer diameter of cable and wire, if their outer diameter is 25 mm or above.
If the diameter of cable and wire is above 25 mm, the curve diameter should be at least 12 times of the outer diameter of the cable and wire.
