3 Core Xlpe Power Cable Copper Conductor Medium Voltage Armored Ground Wire
The maximum operating temperature of cores shall not exceed 90 ℃ when the cable is used for long perod.
The temperature of cores shall not exceed 250 ℃ at short circut for S seconds. The amlient temperature should
not be below O℃ during installation.
The permissible bending radirs for cable shall be the permissible bending radius for cable shalbecomplied .
with the regulation as below:
For single-core No armoured cable:R>20(D+d) ±5% For multi-core:R>15(D-d)±5%
Armouredd cable:R>15(D+d)±5% For multi-core:R>12(D+d)±5%
Where:R-bending radius(mm) D-overall diameter of the cable(mm)
d-diameter of conductor(mm)
The single core cable of using in AC circuit shall be without armor or with steel wire armour an shall not be
laid in magnetic ducts.
