Patent Images
1. A fire-resistant electrical penetrator comprising:
- a body having a first and a second end, the body comprising an insulator;
a conductor disposed within the body;
a metallic sealing element disposed about and fixedly secured to a middle of the body and adapted to be used in a metal joining process; and
a set of metallic end sleeves disposed at the first and second ends of the cylindrical body, joining the conductor to the body;
wherein the conductor extends beyond the first and second ends of the body.

Abstract
The present invention provides a fire-resistant electrical feedthrough system for use in offshore and top-side electrical submersible pump (“ESP”) installations. The fire-resistant electrical feedthrough system includes a minimum of two, redundant pressure barriers, in order to provide for safe operation and increased system reliability. The primary barrier is typically embedded within the wellhead equipment structure, while the secondary barrier is typically externally mounted.
