Concentric Cable
Application: Concentric cable is different from traditional power cables. 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. At present, concentric cable are popular in Africa, USA and Canada. Concentric cable Transmit the electric power does not interfere with the surrounding electrical equipment; also eliminates the external electromagnetic interference connected to the power Cable on the impact of electrical equipment
