Operating Characteristics
Rated voltage: 0.6/1(1.2)kV
Max. permissible continuous operating temperature of conductor: 70oC
Max. temperature of conductor during short-circuit (5s max. duration) shall not exceed:
Nominal cross section of conductor ≤300mm2: 160 oC;
Nominal cross section of conductor >300mm2: 140 oC
The ambient temperature under installation should not be lower than: 0 oC
The bending radius of cable is recommended as following:
For single core cable: not less than 15 times of the diameter of cable
For multi-core cable: not less than 12 times of the diameter of cable
When the armoured single core cable used for Alternative Current(AC) system, the armour material should be non-magnetic.
Application
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, in tunnel, in cable trench or direct in ground, able to bear external mechanical force, but unable to bear large pulling force.
Manufacturing Standards
GB/T 12706-2008, IEC 60502-1
