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.
