The cable meets the standard requirements of GB/T*********2 or IEC*********7.It is suitable

to be installed in the power line with rated voltage from U0/U(Um) of 3.6/6(7.2)KVto *6/*5(*0.5)KV.

Using properties
Earth fault permissible duration
The operating systems are divided into three categories available for selecting cable

Category A:When any phase is earthed, the cable can be departed from the system within 1 minute.
Category B：The earth fault duration each time does not exceed one hour, the accumulated time shall not exceed **5 hours each year.
Category C: Excluded categories from A and B.                        

The maximum rated temperature
The maximum operating temperature of cores shall not exceed *0℃ when the cable is used for long period. The temperature of cores shall not exceed **0℃ at short circuit for 5 seconds.

Installation requirement
The installation of cables is not limited by the difference of level along the route. The ambient temperature should not be below 0℃ during installation. The permissible bending radius for cable shall not be less than *0 times of the cable diameter. The single cable shall be without amour or with steel wire amour when it is electrified with alternating current and shall not be laid in magnetic ducts.
