Operation characteristic
 The maximum operating temperature of cores shall not exceed 90ºC ween the cable used for a long period. The temperature of cores shall not exceed 250ºC at short circuit for 5 seconds. The ambient temperature should not be below 0ºC during installation.
   The permissible bending radius for cable should be the permissible bending radius for cable shall be complied with the regulation as below:
For single-core No armoured cable: R>20(D+d)±5% For multi-core:R>15(D+d)±5%
            Armoured cable:R>15(D+d)±5% For multi-core:R>12(D+d)±5%
Where:R-being 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 armour or with steel wire armour and shall not be laid in magnetic ducts.
