(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.
