Winding Wire

Submersible Winding Wire

We also offer poly wrapped winding wire commonly known as "Submersible Copper Winding Wire". The copper conductor is wrapped with thin polyster film and Biaxial oriented poly proplyene (BOPP) films. The most modern plant with sophesticated 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
