M. H Classic Submersible Winding Wires
Submersible winding wires are the type of winding wires having close contact with water Or different liquids. In fact many submersible motors are designed in such a way that windings are immersed in the water itself, which works as a cooling media while the pump is in operation.
The continuous extrusion process with on line spark tester gives consistent 100 % checked quality of wire. It can give longer lengths as required by customer. This avoids joints in winding and reduces winding process scrap and integrity of the windings. The superior surface properties with extra softness give an excellent ease of slot filling, and shaping.
