Application

3 Core flat cables are manufactured for critical space requirement, protection against indefinite immersion in water under specified conditions, protection against rain-water and against ingress of small foreign bodies. These cables are used for connecting the submersible pump motors to the power source.

Standard

3 Core flat Cables are strictly manufactured as per IS 694 : 1990.

Construction

3 core Flat cables are produced from the bright annealed flexible electrolytic copper conductor, which is drawn, annealed on-line and bunched on automatic machines to ensure flexibility and uniform resistance. The conductors are insulated with a special grade of PVC on sophisticated co-extrusion lines. The Outer sheath of the cable is made from special grade of abrasion resistance PVC compound impervious to grease, oil and water etc.
