1KV Medium voltage underground power cable manufacture from China

5. Opearting Characteristics

Rated voltage U₀/U(U_m): 38/66(725.)KV (Underground XLPE High Voltage Power Cable)

U₀ is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
U is the rated power frequency voltage between conductors for which the cable is designed;
U_m is the maximum value of the “highest system voltage” for which the equipment may be used.
Max. permissible continuous operating temperature of conductor: 90 °C
Max. temperature of conductor during short-circuit (5s max. duration) shall not exceed: 250 °C
The ambient temperature under installation should not be lower than: 0 °C
The bending radius of cable: not less than 20 times of the diameter of cable

Quality Assurance:

With Yiteng, all cables are produced by strict inspection and testing:

1). Raw Material: Copper, Aluminium, PVC, PE and XLPE granules and all other materials for producing cables are all inspected carefully automatically. Only the qualified will be applied into cable production, the disqualified will be rejected.

2). Production Procedure: Cables in Yiteng are produced by advanced cable production machines.

3). Testing: Cables in Yiteng will not be packed until they are tested totally qualified. Cable Testing Machines includes Online Core Shift Detection Device, Tension Tester, Aging Test Chamber, Experimental Apparatus of Combustion, Insulation Resistance Tester and etc…
