2. Operating Characteristics
Rated voltage U0/U(Um): 8.7/15(17.5)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 20 times of the diameter of cable
For three core cable: not less than 15 times of the diameter of cable
3. Application
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel or in cable trench, unable to bear external mechanical force.
Single core cable in magnetic duct is not permissible.
