Submersible 3 Core Flat Cables

For trouble free working, this connecting cable is used for submersible pump motors. Submersible 3 Core Flat Cables are manufactured keeping in mind the severe and difficult conditions in which they are required to perform. The individual conductors are made of bright electrolytic grade copper . These wires are drawn, annealed and bunched properly to ensure flexibility and uniform resistance. Each of the 3 copper conductors is insulated with special PVC Compound. The cores are laid up in flat parallel position. The outer sheath of the cable is made from a special grade of abrasion resistance PVC Compound impervious to water , grease, oil etc.
