Abstract
A system and method for enhanced magnet wire insulation is described. The system of the invention provides an enhanced insulation for magnet wire that is capable of withstanding high temperatures and provides a seal against water that is needed in electric submersible pump (ESP) applications. The enhanced insulation of the system of the invention provides the dielectric advantages of polyimide tape, such as Kapton tape, while also including the advantages of organic polymer thermoplastic insulation that prevents the delaminating at high temperatures that may occur in pumping applications using a variety of electrical submersible motors.
Claims6
An electric submersible pump system employing an enhanced magnet wire insulation, the system comprising:
- a pump;
- an induction motor suitable for use as an electric submersible motor, the induction motor coupled to the pump so as to turn the pump;
- a magnet wire windingly coupled to the electric submersible motor, the magnet wire comprising enhanced insulation suiting it for use in temperatures of about and above 550° Fahrenheit, the enhanced insulation further comprising a layer of polyimide tape coupled to the magnet wire and the layer of polyimide tape further encased within a layer of organic polymer thermoplastic insulation.
A method of making an enhanced magnet wire insulation suited for an electric submersible pump application, the method comprising:
- drawing copper magnet wire to size;
- cleaning the copper magnet wire;
- pulling the copper magnet wire through a polyimide wrap machine to produce wrapped copper magnet wire;
- redrawing the wrapped copper magnet wire through an extrusion mold, applying molten organic polymer thermoplastic to the wrapped copper magnet wire to produce enhanced magnet wire;
- winding the enhanced magnet wire into an induction motor to be used in connection with an electric submersible pump.
