Claims15
A lead wire comprising:
- a solid copper conductor;
- and
- solid insulation extruded about the conductor.
A method of forming a lead wire for an electric submersible pump, the method comprising:
- providing a conductor;
- and
- extruding solid insulation about the conductor.
A stator for an electric submersible pump motor, the stator comprising:
- a housing;
- a plurality of laminations forming a lamination stack within the housing;
- slots extending axially through the lamination stack;
- windings extending axially through the slots;
- an end turn area at a top end of the lamination stack in which the windings extend generally circumferentially;
- encapsulation material surrounding the windings in the end turn area;
- and
- a plurality of lead wires coupled to the windings and extending upward from the end turn area, each lead wire of the plurality of lead wires comprising:
- a solid copper conductor;
- and
- rigid, high temperature, solid insulation extruded about the conductor.
