Multicore Flat Cables
|
|
The PVC insulated and sheathed multicore 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.
Manufactured from bright-annealed 99.97% pure bare copper conductors these cables have low conductor resistance. The inner cores are insulated with a special grade PVC compound. The tough outer PVC jacket protects it from oils, greases, various chemicals and abrasions, thereby giving long life and electrical
safety.
