Grounded surface distribution apparatus

A plug-in type encapsulated electrical component for installation at a point along the length of a medium-voltage supply cable between the ends thereof, comprising

• a circuit element to be protected,
• a defined mass of electrically insulating material surrounding and enclosing said circuit element to protect it,
• a first connector comprising at least a first power lead sealed to said mass of electrically insulating material with the first lead in electrical connection with the circuit element, and
• a second connector comprising at least a second power lead adapted to be sealed to the cable with the second lead in electrical connection with the cable, said first and second connectors being releasably and re-engageably mating with each other with the first lead in electrical connection with the second lead to electrically couple the cable to said circuit element and to form a continuous vapor-proof electrical insulation between said mass of electrically insulating material and the cable, all electrical power lead connections to said circuit element being electrically insulated to withstand hostile fluid immersion of said connections at the voltage levels imposed on said connectors, whereby the component may be installed directly in a run of of the cable in a hostile environment in total insulation without the need of further enclosure against the hostile environment.
