3 Core Flat Submersible Connection Cables are made from annealed high conductivity electrolytic stranded copper wires. These Cables are designed to give connection in submersible pumps because the area of installation is physically restrictive. These Connection Cables have the conductor insulated with polyester to decrease overall diameter of cable. 3 Core Flat Submersible Connection Cables combine features like high electrical strength, superior space factor, very low water absorption, high abrasion resistance and mechanical strength.
