Standard

The cable is manufacture according to the require ment of chiese standard GB12706-91or IEC60502-1994,and BS DIN and ICEA.and suitable to be installed in electrical power transmission and distribution lines voltage(Uo/U)0.6/1KV.

pvc insulation pvc sheath power cable

Application

(1)    Rate voltage Uo/U is 0.6/1KV

(2)    Maximum rate temperature of cable conductor is 70°C

(3)    Maximum rated temperature is lower than 160°C when cable is shorted for less 5 senconds.

(4)    Ambient temperature is not lower than 0°C and its minimum bending radius is as follow when cable is installed:

For single core -20(D+d),umit:millimeter

For multi-core 15(D+d),imit:millimeter

Note:D denotes the overall diameter of cable,while d means the nominal diameter diameter of the main conductor,Unit:millimeter     

Key Technical Parameter

Calculation condition of capacity

Ambient temperature is 25°C

Conductor working temperature is 70°C

Soil heat resistance coefficient is 1.0°C.m/W,but not consider its rise resulted from water migration when it operates continuously.

Gap between axis of cable and surface of ground is 1000millimeter when it is laid in ground

For multi-core cable,gap of axis of cable is 3 times O.D..
