MV 11kv Copper XLPE Power Cable - Operating Characteristics
Rated voltage U0/U(Um): 6/10kV
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;
Um 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 is recommended as following:
For single core cable: Not less than 15 times of the diameter of cable
For three core cable: Not less than 12 times of the diameter of cable
When the armored single core cable used for Alternative Current(AC) system, the armoring material should be non-magnetic.

MV 11kv Copper XLPE Power Cable - Application
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force and certain pulling force.
The xlpe power cable can be produce according to the standard IEC 60502. Our factory can also design and manufacture special XLPE cable according to the other standards required by the customers'. They not only have excellent electric conductivity mechanical properties, but also have powerful resistance against chemical corrosion, heating and environmental stress. Their structures are simple. The permissible maximum operating temperature is 90°C. It is convenient for using and they can be laid with no restriction of different elevation.
4. Manufacturing Standards
IEC 60502-2 and Chinese National Standard GB/T 12706-2008 We can produce above cables according to popular international standards such as ASTM, BS, DIN, NF &AS/NZ also.
