Standards

The cable meets the standard requirements of GB/T12706-2002 or IEC60502-1997.It is suitable

to be installed in the power line with rated voltage from U0/U(Um) of 3.6/6(7.2)KVto 26/35(40.5)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 125 hours each year.

Category C: Excluded categories from A and B.                        

The maximum rated temperature

The maximum operating temperature of cores shall not exceed 90℃ when the cable is used for long period. The temperature of cores shall not exceed 250℃ 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 10 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.

Core wire for ACSR is available with Class A, B or C galvanizing; "aluminized" aluminum coated (AZ); or aluminum clad (AW).

Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
