Abstract
An electrical penetrator assembly is shown, configured to feed electrical voltage and current through a wall separating a first volume and a second volume, which may have different pressure and/or may be filled with different fluids. The connector comprises a wall or partition having a through opening. An electrical conductor surrounded by a tubular insulator body passes the opening through the wall. A conductive or semi-conductive coating is arranged on the exterior of the insulator body, the coating surrounding the insulator body for a portion of its length, the coating in electrical contact with the wall, wherein the coated portion of the insulator body is shaped to displace the electric field around the conductor away from the wall and reduce the electric field strength around the insulator body by increasing the electric field strength inside the insulator body.
