Polywrap Winding Wire

COPTECH WIRE INDUSTRY (CWI) Makes Polywrapped submersible winding wires with its state of art manufacturing plant located at Coimbatore, India. Polywrapped wires manufacturing plant is equipped with latest automated machineries which produce the best quality products with stringent process and quality control activities.

Conductor

Conductor are made from electrolytic grade with more than 100% conductivity and > 99.95 % purity copper material. Copper rod is converted into solid wires and annealed for better flexibility , annealing is carried by Online annealing method . By giving the good annealing at conductor, we ensure the product flexibility at end application in terms of easy winding, shaping in Submersible product assembly , it saves end user assembly time , increase production, reduce reworks.

Insulation

Annealed copper conductor insulated with three layers of Film papers. The First layer over the conductor will be Polyester, 2nd layer Bi-axially oriented polypropylene opaque white, 3rd layer Bi-axially oriented polypropylene transparent films. All three films are sequentially wrapped over conductor and passed through oven for sealing together and form good insulation. The Raw material which we use for ,

  • Polyester films having excellent electrical, mechanical, Thermal properties.
  • BOPP Opaque white & transparent films will have , Excellent opacity, Gloss surface, Excellent hot take and heat seal strength, Excellent Mechanical properties , Good Barrier properties

We producing the winding wire in two sequence of insulation based on customer requirements,

1 st – Polyester, BOPP White, BOPP transparent
2 nd – BOPP transparent, BOPP White, BOPP transparent
