1. AC rated voltage:
Uo / U = 450V / 750V;
Uo: the effective value of voltage between any phase conductor and ground;
U: The effective value of voltage between any two phase conductors.
2. Operating voltage:
In the AC system, the working voltage is not greater than 1.1 times the rated voltage;
In DC systems, the operating voltage is not greater than 1.5 times the rated voltage.
3. Long-term working temperature of wire core: less than or equal to 65 ℃.
