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.
