Palywin from Khandelwal cable PVC /Polywrapped winding wire for submersible motors |
|
Polywin winding wires having an outstanding Electrical, Mechanical, Thermal and Chemical properties. These are quite sturdy, robust and miniaturized too. These are not only fulfill the requirement of all available standards but even more better in many respects. These winding wires can withstand water abrasion and frictional losses, saves space/size, cost and work in every type of typical conditions. In brief the details are as follows: |
|
| |
|
|
| The structure of insulation is oriented bi-axially. Propagation of tears is difficult. Uniaxial orientation makes it easy to tear the insulation along the axis of the wire. |
|
|
The multiple layer construction of Polywin insures high dielectric quality of insulation. Any flow is limited to a single layer of the tape. The wrapping process places the insulation concentrically around the conductor. |
| |
Higher Cut Through & Abrasion Resistant |
|
Polywin insulation is remarkable resistant to cut through and scrap abrasion. Thin cross sections of Polywin 0.15 to 0.25 mm thick will endure greater cut through stress and general abuse than 0.25 to 1.0 mm of insulation such as PVC, Nylon jacketed PVC. |
|
| |
|
Polywin insulation adds significantly to the tensile strength of the insulated conductor through the mechanism of load transfer because the insulation has such a superior breaking strength. It will support the wire at each point where excessive stretching occurs. Wire insulates with conventional materials will break since there is no support from insulation. |

|
For short periods +130° C
Continuous -60° C to +120° C |
|
| |
|
| The insulation is produced by biaxially oriented synthetic film. It has very high flex life in comparison to any other insulating materials. |
|
| |
|
| It has remarkable constant & thousands time higher insulation resistance even at boiling point of water than PVC. |
