Usage characteristics:

①Long-term allowable working temperature of the cable: PVC insulation is 70°C; polyethylene insulation is 70°C; cross-linked polyethylene insulation is 90°C.

②Short-term maximum working temperature of the cable: during a short circuit (5s); PVC insulation is 160°C; polyethylene insulation is 130°C; cross-linked polyethylene insulation is 250°C.

③The cable installation temperature should not be lower than -20°C.

④The cable operating ambient temperature is -40°C ~ 40°C, with relative humidity not less than 90% during the rainy season.

⑤Allowable bending radius of the cable:
For cables with a rated voltage of 0.6/1kV and below:

If the cable outer diameter D < 25mm, the bending radius should be no less than 4D.

If the cable outer diameter D ≥ 25mm, the bending radius should be no less than 6D.
For cables with a rated voltage of 10kV:

For single-core cables, the bending radius should be no less than 20(D+d)mm.

For multi-core cables, the bending radius should be no less than 15(D+d)mm.

Among them:
D - the actual outer diameter of the cable in mm;
d - the actual outer diameter of the cable conductor in mm.
