Abstract
Abstract The conduit or covering of a pressurized cable system is dammed on both sides of a splice, and a by-pass conduit provides a pressure system around the splice. A covering or case over the splice is pressurized from the by-pass to a lesser pressure than that in the main conduit, but still providing a moisture proof covering for the splice.

Total Claims: 2
Claim 1
Independent Claim
167 words
A pressurized cable splice comprising in combination with one pressurized cable having extending wires spliced to corresponding wires extending from two cables and all said cables having a pressurizable covering: of a splice case sealed in pressure tight relation to the cables at each end with the end of each cable covering terminating in said splice case; a dam on each end of each cable sealing said covering in a pressure holding seal on each said end and around the protruding wires; a by-pass conduit connected to said one cable at one end of said splice case and to said two cables at the other end including a connector mounted between said two cables for simultaneously pressurizing both Said cables, each connection being on the cable side of said dams whereby said by-pass communicates with said pressurizable cables; and regulating valve means in by-pass communicating wth the interior of said splice case, for pressurizing said splice case at a pressure lower than the pressure in said cables.
