Tree-deterioration mechanism of water immersed polyethylene coated wire and its improvement of the insulation life

In recent years, submersible pumping units have been winning greater recognition for their economy and their good performance properties. As a result, they have found wide use in the manufacturing industries. One insulating system of submersible motors is the type in which insulating wires are wound for the stator, and wires coated with polyethylene are often used as the insulating wires in this case.
