Patent number: 8772997Abstract: 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 film 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 motor contains a PAO oil having additives to dissipate acid generated by epoxy used in the motor.Type: GrantFiled: May 16, 2011Date of Patent: July 8, 2014Assignee: Baker Hughes IncorporatedInventors: Michael R. Rumbaugh, Jim F. Evenson, Jackson E. Reynolds, David G. Korte, David W. Livingston, Jeffrey G. Frey

Patent number: 6969940Abstract: An electric motor has a housing with a plurality of stator discs. The discs have slots that align with one another, forming passages. A dielectric film tube inserts into the slots, each of the tubes having a continuous circumference. Each tube has a nonmeltable dielectric film layer of high temperature insulation. The dielectric film layer has overlapping edges and is bonded to a carrier layer of a meltable material. The tubes may be inserted into the slot passages by drawing a vacuum in the interior of each tube, causing it to collapse so that it can be readily inserted.Type: GrantFiled: July 8, 2003Date of Patent: November 29, 2005Assignee: Baker Hughes IncorporatedInventors: Larry V. Dalrymple, David G. Korte, L. Wayne Pyron, George C. Soukup

Patent number: 6103031Abstract: Conductors are placed in insulator which acts as a spacer/centralizer for the conductors, which are in turn mounted within tubing. The void spaces between the insulator and the tubing inside wall can be filled with a sealing material. Alternatively, the voids around the substantially centralized conductors can be used as flow channels for the transmission of fluid pressure to a remote location, such as downhole. The conductors are protected because they are kept away from the tubing wall and can be further protected by the addition of the sealing material.Type: GrantFiled: November 3, 1998Date of Patent: August 15, 2000Assignee: Baker Hughes IncorporatedInventors: William Edward Aeschbacher, David G. Korte, Larry V. Dalrymple

Patent number: 5426264Abstract: An electrical cable for use in submersible well pumps in oil and gas well environments is provided having an electrical conductor core which is surrounded by an insulating layer of cross-linked polyethylene. A barrier layer surrounds the cross-linked polyethylene insulating layer. The barrier layer is impermeable to oil and other liquid hydrocarbons, but is permeable to low molecular gases. The barrier layer is preferably formed from a fluoropolymer and is surrounded by a polymeric protective layer. An adhesive layer attaches the barrier layer to the insulating layer.Type: GrantFiled: January 18, 1994Date of Patent: June 20, 1995Assignee: Baker Hughes IncorporatedInventors: David W.
