Modern-day water systems survive on submersible pump motors, and at the core of it all is something most people will tell you that they do not know anything about: winding wire. Whether it is for domestic borewells, irrigation, or industrial water supply, the correct winding of copper wire in the submersible pump motor helps make it efficient, long-lasting, and safe.
Bharat Insulation Company is one of the prominent manufacturers and exporters, and deal with high-performance-grade copper winding and wires that are specifically used in submersible motors. Our products offer a large diversity of electrical motor applications and serve this diverse market with ISI-grade standards of manufacturing and industry-proven reliability.
Submersible motors operate under demanding conditions, remaining constantly submerged in water and exposed to extreme pressure and temperature fluctuations. Using low-quality winding wires can lead to serious issues such as motor failure, frequent maintenance or rewinding, and reduced operational efficiency.

BIC magnet wire for submersible pump motors and submersible motor wire insulation options are optimised for both domestic and industrial-grade pumps.
Enameled copper wires or polywrapped, dual-coated copper wires are well suited because they are water-rated, thermally highly rated, and mechanically strong, thus most submersible pumps have this.
Look at the ISI mark, label of the manufacturer, and resistance per meter. Bharat Insulation Company Wires are supplied on uniform labelled and quality assured material.
And with the rewinding wire of submersible pump motors that are of original specification, yes. Always ensure that you use copper winding wire which is resistant to heat so that it cannot fail prematurely.
There is one enamel layer of insulation in super enameled wire. Two-layer coated wire (dual coated wire) provides increased abrasion protection, chemical resistance and temperature resistance and is suited to heavy-duty motors.
Yes, in the case of polywrap and a dual-coated copper wire, the waterproofing ability was specifically conceived with the idea of ensuring that the integrity of insulation remains intact, even after years of being submerged into water.
