2、 Product technical requirements
Usage characteristics
1.1 Rated voltage:
U0/U is 450/750V, 300/300V, and 300/500V;
1.2 Working temperature:
The long-term allowable working temperatures for cables and wires are 70 ℃ and 90 ℃.
1.3 Laying temperature:
The laying temperature of cables and wires should not be lower than 0 ℃, and they should generally be laid through pipes;
1.4 Bending radius:
For cables with an outer diameter (D) ≤ 25mm, the small allowable bending radius is 4D;
If the outer diameter (D) of the cable is ≥ 25mm, the small allowable bending radius is 6D;
1.5 Scope of application:
