We also manufacture poly wrapped winding wires commonly known as “Submersible Copper Winding Wire”. The round copper conductor is wrapped with a Polyester or Transparent BOPP film overwrapped with Biaxial Oriented Poly Propylene (BOPP) films. The most modern plant with sophisticated wrapping heads and 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 (Part 4/Sec3) .
Following sizes are routinely manufactured by us . Apart from these sizes , sizes as per customers requirement can also be manufactured .
