Abstract: A cable includes an outer jacket of polyethylene surrounding a plurality of conductive wires. Each one of the plurality of insulated conductive wires comprises a conductive core and an insulating layer surrounding the conductive core, the insulating layer being made of cross-linked polyethylene.

Abstract: A cable and corresponding method for making a cable are provided. The cable includes an outer jacket of polyethylene surrounding a plurality of conductive wires. Each one of the plurality of insulated conductive wires comprises a conductive core and an insulating layer surrounding the conductive core, the insulating layer being made of cross-linked polyethylene.

Abstract: A pressure vessel is provided for housing electronic components in an underwater environment and permitting connection of the components to signal transmission elements of a signal cable. The pressure vessel comprises a hollow steel shell defining an interior chamber adapted to house the electronic components. A layer of thermal-sprayed aluminum covers the shell. The shell has an opening adapted to pass the signal transmission elements into the interior chamber. A seal adapted to sealingly surround the transmission elements is disposed in the opening in the shell so that an outer peripheral surface of the seal contacts an inner peripheral surface of the opening in the shell for preventing moisture penetration into the interior chamber. The seal may be formed of epoxy and the outer peripheral surface have a plurality of compressible o-rings disposed in axially-spaced circumferential grooves for contacting the inner peripheral surface of the opening in the shell.

Abstract: A cable seal and method for sealing a cable termination is provided for sealing the passage of a cable into a cable-receiving structure. The seal includes a first plurality of o-rings disposed along a length of the cable adjacent the cable-receiving structure and a first length of heat-shrinkable tube which fits over the cable and o-rings for compressive engagement with the cable and o-rings to prevent moisture penetration between an inner surface of the first tube and the outer surface of the cable. A second plurality of o-rings is disposed over the first heat-shrinkable tube adjacent the first plurality of o-rings.
