Winding Wires & 3 Core Flat Cables

PVC insulated winding wires are used as original equipment for winding of submersible pump motors. They are also used for rewinding of these motors. The special purpose PVC insulation enables these wires to operate under water over long periods. The minimum insulation thickness is achieved through precision extrusion process so that insertion in stator slots is smooth and easy. Finolex has also developed higher sizes with multi strand copper conductors for higher HP Pump motors for specialized applications such as de-watering, mining and naval pumps. The conductor is solid/stranded and is manufactured from bright-annealed 99.97% pure bare copper which offers low conductor resistance. These wires are insulated with a special tough grade PVC compound formulated and manufactured in-house which is impervious to water, oil, grease, acids etc. These wires are extruded on state of the art machines for concentric insulation. Each coil is put through quality checks and water immersion test for trouble free marathon performance. These wires conform to IS 8783 (Part 4 / Sec 1) : 1995 and have lower overall diameter.
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. 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 formulated and manufactured in-house. The tough robust outer PVC jacket protects it from the oils, greases, various chemicals and abrasions, thereby giving long life and electrical safety.
