Products Submersible Copper Winding Wire
Submersible Copper Winding Wire
Polyester-wrapped conductor for deep-well pump motors. Moisture- and corrosion-resistant, stable to 200 °C.
Wet-wound submersible pump motors run with the winding immersed in water, so the wire has to be its own insulation system. We wrap a bare or enamelled copper conductor with a polyester film and extrude a modified polyester or PVC jacket over it, giving a smooth, tightly bonded covering that resists water absorption, oil and abrasion during winding.
The result is a wire that keeps its dielectric strength after long immersion and repeated thermal cycling, which is what a pump buried a hundred metres down needs. Sizes are held to the overall diameters in our submersible table so slot fill stays predictable.
