2. Operating Characteristics
Rated voltage U0/U(Um): 6.35/11(12)kV
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 armored material should be non- magnetic.
3. Application
This kind of 11kv XLPE insulated STA copper 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, but unable to bear large pulling force.
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.
