Electrical feedthrough for subsea submersible well pump in canister

摘要

A subsea pump assembly includes a tubular conduit that has an upstream end plate and an inlet for flowing well fluid into an interior of the conduit. A power cable opening extends through the upstream end plate. An electrical submersible pump and motor are in the interior of the conduit. The motor has a motor assembly housing with an upstream end having an electrical insulator opening. An end connection secures the upstream end to an interior side of the upstream end plate with the insulator opening registering with the power cable opening. An insulated electrical connector is mounted in the insulator opening. A motor wire in the motor assembly housing joins to an inner end of the electrical connector. A power conductor extends from exterior of the conduit through the power cable opening and joins to an outer end of the electrical connector.
