Concentric Cable
Application
The construction of this cable is different from traditional ones.It uses one core from the 2 or 3 cores cables as the shielding layer,which is twisted over the insulation or inner sheath of one core.The core inside is the main core when application,and the core twisted outside is the neutral core.It saves one layer insulation,and makes the overall diameter much smaller.It is calculated that the cost is saved by 10-15%.At present,cables with this construction are popular in Africa,USA and Canada.Transmission of electricity,will not interfere with the surrounding electrical equipment;also eliminates the external electromagnetic interference connected to the power Cable on the impact of electrical equipment.
Applicable Standards
SANS 1507-6 AS/NZS 4961 HD603 HD626 ICEA S-66-524 KS04-1022 VDE 0276-603 or the standards agreed by both of the customers and us.
