Winding Wires

We proudly presents the winding wire commonly known as "SUBMERSIBLE COPPER WINDING WIRE." The copper conductor is wrapped with thin polyester film & Biaxial Oriented Poly Propylene (BOPP) films. The modern plant with sophisticated wrapping heads & inline continuous heat shrinkage furance 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.

Applications

Used in submersible pump motors of all sizes for domestic and industrial.

Packings

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

Testing Facilities For Submersible Winding Wires

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

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 tensile 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)
