PVC insulated Winding Wires for Submersible Pump Motors

Application
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.

Features
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 and have lower overall diameter.

Thin Wall Polymer Insulated Winding Wires for Submersible Pump Motors

Application
These winding wires have very thin insulation thickness which makes them useful in smaller submersible pumps such as V4 pumps. The old pumps are to be rewound the stator slots get smaller and they require thinner winding wires.

Features
Made from bright-annealed 99.97% pure bare copper conductors these wires have low conductor resistance and hence high flux capacity. The thin insulation thickness is achieved through precision extrusion of specially developed and manufactured polymeric compound. Each coil is put through quality checks and water immersion test for trouble free marathon performance.
