  • Submersible Winding Wires

Submersible Winding Wires manufactured by us have an outstanding Electrical, Mechanical, Thermal and Chemical properties. Our Submersible Winding Wires not only fulfill the requirements of all available standards but even better in many respects. Submersible Winding Wires manufactured by us are tear resistant because of their bi-axial orientation. The multiple layer construction of these wires insures high dielectric quality of insulation. The insulation also adds significantly to the tensile strengths of the wire which supports the wire at every point whenever excessive stretching occurs. These winding wires have passed test standards of IS: 8783 -2000 Part IV Sec -3. Polywin Submersible Winding Wires are far more superior than conventional type of winding wire. It is self explanatory by the following comparative chart.

Name of test Value specified in standards for PVC insulated winding wire Values obtained on Polywin (Polymer Insulated) winding wire Remarks
Thickness of Insulation 0.35 mm 0.20 mm Approx. 40% minitiarised
Heat shock test The insulation shall not show any crack Satisfactory Ok
High Voltage test To withstand 3KV(rms) for one minute Withstood Ok
Shrinkage test The shrinkage shall not exceed 4% 3.5% Ok
Insulation resistance (VoltageResistivity) Ohm-cm
    1. At 27°C 1.28 x 10 13 6.18 x 10 16 Far Superior
    2. At 70°C 1.28 x 10 13 55.03 x 10 14 Far Superior
    3. At 85°C 1.46 x 10 9 20.63 x 10 14 Far Superior
    4. At 100°C 1.46 x 10 9 41.27 x 10 13 Far Superior

On specific demand, Polywin winding wire can be produced in Multistranded, Flexible construction. Presently our Polywin winding wires are being used by all the reputed manufacturers in India in their submersible pumps ranging from 0.5 H.P. to 250 H.P. satisfactorily.
