4 Core Aluminium Conductor Steel Wire Swa Armoured Power Cable
Product Description
1. Operating Characteristics of cable swa
Rated voltage: 0.6/1(1.2)kV
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 multi-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.
2. Application of steel wire armoured cable
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid in high fall area, able to bear external mechanical force, and certain pulling force.
3. Manufacturing Standards of 4 core armoured cable.
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.
