Submersible 3 - Core Flat Cables
Our Submersible 3 - Core Flat Cables are a specialized product, which is used for submersible pumps in deep wells. The environment is very uncongenial and also area of installation is physically restrictive. Kundan cab Submersible 3 - Core Flat Cables are manufactured and designed to attain the highest possible degree of reliability and meet the above factors.

Range of Submersible 3 - Core Flat Cables 1.5 Sq mm to 50 Sq mm Submersible 3 - Core Flat Cables

These cables are manufactured keeping in mind the severe and difficult conditions in which they are required to perform. They are made from bright electrolytic grade copper. Proper care is taken during the manufacturing process to ensure flexibility and uniform resistance. They are properly drawn, annealed and bunched in order to maximize their performance. Special PVC compound is used to insulate each of the 3 copper conductors from each other. The cores are laid up in flat parallel position. Finally, the outer sheath of the cable is made from a special grade of abrasion resistance PVC compound, which is impervious to water, grease, oil etc.
