Abstract
An arrangement to conduct electrical power from a non-hazardous area through plural electrical conductors to the electrical conductor of a power cable which extend through a sealed barrier in a wellhead in a hazardous area including a rigid conduit with a power source electrical conductor therein extending into the hazardous area from an adjacent non-hazardous area for conducting electrical power to a downhole electrical conductor in the hazardous area, said rigid conduit including a seal fitting, splice fitting connected with said seal fitting and positioned adjacent the wellhead for receiving the ends of the power source electrical conductor and the ends of the downhole electrical conductor extend through the sealed barrier in the wellhead for splicing them together. The seal fitting includes a seal within 18 inches downstream of the splice fitting and also includes a breather for discharge of fluid and for inhibiting an internal explosion, flame or fire within the arrangement from exiting into the hazardous area.
