More product about LV Power CableProduct Description
1. Operating Characteristics
Rated voltage: 0.6/1(1.2)kV
Max. Permissible continuous operating temperature of conductor: 70° C
Max. Temperature of conductor during short-circuit (5s max. Duration) shall not exceed:
Nominal cross section of conductor ≤ 300mm2: 160° C;
Nominal cross section of conductor >300mm2: 140° 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 multi-core cable: Not less than 15 times of the diameter of cable
2. 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 in conduit, unable to bear external mechanical force.
3. Manufacturing Standards
IEC 60502-1 & 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.
