Use characteristics of PVC insulated and PVC sheathed power cables
1) The maximum rated temperature of the cable conductor is 70℃.
2) The maximum temperature of the cable conductor does not exceed 160°C during short circuit (the longest duration does not exceed 5S).
3) The ambient temperature when laying the cable should not be lower than 0℃, and the minimum bending diameter is twice the diameter of the cylinder used for the cable bending test.
Note: The laying method and reference parameters used to calculate the current carrying capacity of the cable are:
Laying in the air: ambient temperature 40℃;
Laying in soil: The soil thermal resistance coefficient is 1.0k m/w at an ambient temperature of 25°C, and the single-core cables are arranged in a triangle (contact with each other).
