Winding Wires




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 enable these wires to operate under water over long periods. The minimum insulation thickness is achieved through precision extrusion process so that insertion is statos slots is smooth and easy. 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 wire 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 coli 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.

Instructions For Use PVC Insulated Winding Wires

PVC Insulated Winding Wire is a delicate product and its correct application is critical for trouble free performance of the pump. While all due care B taken from manufacturing to packing stage, proper care should be taken during handling, storage and insertion into stator slots to ensure desired product performance.

These wires are subjected to stringent quality checks/ High voltage test is carried out on each and every coil. Repeated tests at the customer’s end should therefore, be avoided only megger test is recommended to be carried at customer’s end.

Ensure that these wire are store at normal room temperature

Don’t store near objects having sharp edges or in areas of high temperature to avoid unintentional damage.

Don’t stock more than 4 to 5 coils as the bottom most coil is likely to get damaged by weight.

Don’t use hammer to give to shape to the bunch of coils to fit them in to the motor. These sires lend themselves easily to be manually moulded into any desired shape.

Ensure proper jointing with 3 core flat cables to avoid failure.
