Description
These submersible flat cable are specially designed to provide distinguished tube like structure for the insulated cores. The wall betwee the cores perfectly separates them from coming in contact with each other and provides better mechanical and electrical strength compared to the traditional submersible flat cables. The knurling on the outer surface makes the cable more durable and provides improved abrasion resistance during handling and installation of these cables.
Application
These cables are mainly used in **submersible pump connections**. They are specially designed keeping in mind the tough and severe conditions in which they are used.
