UNDERWATER ELECTRICAL CONNECTION SYSTEM
An undersea connection system for connecting together at least three high voltage or very high voltage undersea electric cables comprises an outer cage defining a connection space; and a connection fitting comprising a conductive connection electrode that presents a junction node from which there extend at least three branches. Each of the at least three branches of the conductive electrode includes a male terminal portion that is connected to a respective one of the electric cables in a connection zone about which there is mounted a connection sleeve made of pre-molded insulating material that receives, via its ends, firstly the male terminal portion of one of the branches of the conductive electrode, and secondly the connection end of one of the electric cables.
Cover assemblies and methods for covering electrical cables and connections
A method for protecting a cable splice connection including a cable, the cable including an electrical conductor surrounded by a cable insulation layer, includes providing a splice body assembly including: an electrically insulative, elastomeric splice body having an interior surface defining an interior passage; and a layer of a conformable medium pre-mounted on the interior surface of the splice body. The conformable medium is a flowable, electrically insulative material. The method further includes mounting the splice body assembly on the cable splice connection such that the layer of the conformable mastic is interposed between and engages each of the interior surface of the splice body and an opposing interface surface of the cable insulation layer.

COLD-SHRINKABLE PROTECTIVE HOUSING AND METHODS INCLUDING SAME
An article includes a cold-shrinkable protective housing configured to be mounted on a terminated cable. The protective housing includes a housing body and an integral, tubular, electrically insulating rejacketing sleeve. The housing body includes a tubular cable leg, a tubular connector leg extending transversely to the cable leg, and a housing insulation layer formed of an electrically insulating elastomer. The rejacketing sleeve surrounds a portion of the cable leg. The connector leg defines a connector bore. The cable leg defines a cable entrance opening at a proximal end and a cable receiving bore extending from the cable entrance opening to the connector bore at a distal end. The cable receiving bore extends transversely to the connector bore. The rejacketing sleeve includes an extension section configured to extend or be extended in a proximal direction beyond the proximal end of the cable leg to surround a jacket of the cable.
