Abstract
Electric submersible well pumping systems operable in well temperatures of above about 180° C. (356° F.) utilize high temperature electrical insulation. The electrical insulation includes E-base polyimide films or perfluoropolymer TE films on various components. The insulation films are employed around magnet wires that are threaded through slots in the stator. Slot insulation of E-base polyimide or perfluoropolymer TE surrounds the magnet wires in the stator slots. Sheets of E-base polyimide or perfluoropolymer TE film extend around and between phase loops of the magnet wire at the lower end of the stator. The magnet wires in the stator have lead portions that extend The motor contains a PAO oil having additives to dissipate acid generated by epoxy used in the motor.
