Power cable features
(1) Rated voltage Uo/LT is 0.6/1 kV.
(2) Maximum rated temperature of cable conductor is 70 0C.
(3) Maximum conductor temperature is lower than 1600C when cable is shorted for less than 5 seconds.
(4) Ambient temperature is not lower than 0 0C and its minimum bending radius is as follows when cables is installed:
For single-core cable -20 (D+d)
Unit: Millimeter
For multi-core cable15 (D+d)
Unit: Millimeter

The main technical parameters
Calculation condition of capacity
Ambient temperature is 25 0C
Conductor working temperature is 70 0C
When the cable is laid underground, the coefficient of soil heat resistance is g=1.0 0C m/W without considering the phe- nomenon of increased coefficient of soil heat resistance caused by moisture over in a long-term operation of cable.
Gap between axis of cable and surface of ground is 1000 millimeter when is is laid in ground
For mulit-core cable, gap of axis of cables is 3 times O. D.
