Embodiments of the invention provide a ring-style terminal block for supporting electrical connections. The ring-style terminal block includes an annular component having a radially inward facing surface at least partially defined by a first radius, a radially outward facing surface at least partially defined by a second radius larger than the first radius, a top surface extending between the radially inward facing surface and the radially outward facing surface, and a bottom surface. The bottom surface extends between the radially inward facing surface and the radially outward facing surface. The bottom surface is opposite the top surface and separated from the top surface by a thickness. The terminal block also includes a plurality of terminals spaced apart circumferentially and formed integrally within the annular component.

A submersible pumping apparatus for displacing transmission fluid includes a pump operably coupled with a motor. A filter housing is attached to the pump and has a cavity with an inlet aperture extending to an exhaust port of the pump. A fluid filter is engaged with the cavity and has a filter cover with a relief valve disposed within an outlet aperture that extends from the cavity to an exit port on the filter cover. The relief valve is configured to open when a fluid pressure from the exit port reaches a threshold and close when the fluid pressure is below the threshold. A rotor cover is attached to the motor and has a circuit board for operating the motor, such that the rotor cover is configured to prevent the circuit board from being exposed to liquid.

An electrical submersible pumping system includes a pump assembly and a motor assembly. The motor assembly includes a plurality of stator coils and each of the plurality of stator coils comprises magnet wire. The magnet wire includes an inner insulation layer and an outer protective layer. The inner insulation layer is preferably constructed from a high-temperature, epitaxial co-crystallized perfluoropolymer that exhibits favorable resistance to elevated temperatures. The outer protective layer shields the inner insulation layer from mechanical abrasion and contaminants.
