Abstract: A technique facilitates construction of a sealed electrical connector, e.g. sealed pothead assembly. Depending on the application, the electrical connector may be used to connect a power cable and a powered component such as an electric submersible pumping system. The electrical connector comprises at least one connector component and at least one electrical component. An injection molding process is used to construct an injection molded feature sealed to a corresponding component, e.g. to the at least one electrical component.

Abstract: An electric submersible pump motor can include a housing; and a hermetically sealed cavity defined at least in part by the housing that includes at least one material susceptible to hydrolysis, and a polymeric material that includes epitaxial co-crystals of perfluoroalkoxy (PFA) and polytetrafluoroethylene (PTFE). Various other apparatuses, systems, methods, etc., are also disclosed.

Abstract: A technique facilitates the provision of electrical power in harsh environments, such as subterranean environments. The technique employs a power cable having at least one conductor and a polyimide insulation layer disposed about the conductor. A fluoropolymer tape layer is disposed about the polyimide insulation layer. The fluoropolymer tape layer is processed into a uniform, bonded layer. Additional cable layers also may be employed to help provide protection in the harsh environment.

Abstract: Representative implementations of devices and techniques provide a tape adhesion test system. The test system applies a pulling force to an outer layer of tape adhered to an inner layer of tape through an adhesive bond, while the inner layer of tape is secured to a portion of the test system. The pulling force is measured when the adhesive bond between the outer layer of tape and the inner layer of tape breaks.

Abstract: A self steering axle system for motor coaches and similar commercial vehicles having a truss which hingedly supports an axle beam for pivotal movement between a normal positive caster angle and a negative caster angle when the vehicle is driven in reverse. The pivotal or rocking movement is achieved by a centrally positioned shift actuator acting through a yoke arm assembly and a latch which absorbs brake reaction forces. The system includes a caster lock for rendering the axle non-steerable in the event of a system failure or above predetermined operational speeds.
