摘要 |
The present invention relates to a transition for electrical well cable through the wellhead barrier of an underground well leading to an electrical power cable connected to an above-ground electrical power source, where the only connection between the electrical well cable and the electrical power cable is formed outside the wellhead barrier within an area adjacent to the wellhead barrier classified as a hazardous location, the connection being listed and approved for hazardous locations by a nationally recognized testing laboratory, and a method of forming the transition. A confined seal is located in the well around the electrical well cable for blocking the flow of fluid both into and out of the well.
