Features:

1. Rated voltage: U. /U is 8.7/15kV;

2. Laying requirements: fixed laying; the external temperature should not be lower than 0°C;

3. The maximum allowable working temperature of the power cable conductor for a long time: no more than 90°C;

4. The maximum temperature of the cable conductor during short circuit (the longest duration is not more than 5s): not more than 250°C;

5. The bending radius is as follows:

project	single core cable		three-core cable
project	no armor	Armored	no armor	Armored
Cable minimum bending radius during installation	20D	15D	15D	12D
Minimum bend radius for cables close to connection boxes and terminals (But the bending should be carefully controlled, such as using a forming guide)	15D	12D	12D	10D
Note: D is the outer diameter of the cable.
