Submersible Winding Wire

We offer poly wrapped winding wire commonly known as "Submersible winding wire". The copper conductor is wrapped with thin polyster film and Biaxial Oriented Poly Proplyene (BOPP) films. The most modern plant with sophisticated wrapping heads and in line continuous heat shrinkage furnace is installed to get uniform covering. A complete quality assurance testing by instruments covering all governing standards is available.

The test standards followed are IS 8783:1995.

Application

Used in submersible pumps motors of all sizes for domestic and industrial applications:

Packaging

Available in coil form with suitable length as per size, in polythene bag and packed in inner and outer corrugated boxes.

Special Salient Features

  • Saves energy ETP grade high conductivity annealed copper used
  • Less current leakage No air gap between the films
  • Tear resistant-High mechanical strength High tenstile strength
  • Each coil tested at 3500 V
  • Heat shock test at 150°C
  • Easy winding-Resistance annealed copper and controlled OD
  • Manufactured by ultra modern automatic plant as per IS 8783 (Part 4/Sec. 3)

Testing Facilities For Submersible Winding Wires

The quality assurance having all the testing facilities with ultra modern, high precision instruments and rigorous testing plans. Details of test which conforms to IS 8783 (Part 4/Sec. 3) is as follows:
