Submersible Flat Cables

Submersible flat cables are important accessories supplied along with the submersible pump. Flat cable provides the electrical supply to operate the pump. Good insulation properties and longer life is the technical demand from submersible flat cables.

From the beginning, flat cables have been developed with PVC insulation, which are having thicker insulations for getting required electrical properties. PVC cables are bulky and tend to lose the insulation properties over period of time. The thicknesses must be added to get the desired level of insulation, this cause more weight of wire and compromise the flexibility.

The PVC insulated and sheathed 3 core flat cables are used for giving electrical connection to the submersible pump motors. These are manufactured keeping in mind the severe, tough and difficult conditions in which they have to operate. The slot available in the tube well being narrow the shape of the cables has to be suited for such an application. These cables conform to and are marked IS 694: 1990 up to 4.0 sq. mm. The sizes above 4.0 sq.mm. cables generally conform to IS 694 : 1990.

Specifications

To manufacture submersible flat cables, the insulated cores are laid up side by side to from a flat oblong shape. Inner cores are coded for identification as per National/International coding system or as per customer's specifications.
