Motor lead with heat deflecting layer for submersible well pump

A motor lead extends alongside an electrical pump assembly for supplying electrical power to the motor. The motor lead has electrical power wires positioned side-by-side in a sub assembly. Each of the electrical power wires has an electrical conductor encased in an insulation layer, which in turn is...

Beschreibung
Zusammenfassung:	A motor lead extends alongside an electrical pump assembly for supplying electrical power to the motor. The motor lead has electrical power wires positioned side-by-side in a sub assembly. Each of the electrical power wires has an electrical conductor encased in an insulation layer, which in turn is encased in a lead sheath. A metallic band armor wraps around the sub assembly. A thermal barrier layer is located between an inward facing side of the sub assembly and the pump assembly. The thermal barrier layer is formed of thermal insulation material and has a width at least equal to a width of the sub assembly. The motor lead is free of any thermal barrier layers on the outward facing side of the sub assembly to as to allow heat within the sub assembly to dissipate outward.
