Embodiments of a cable connector are provided that include an inner connector assembly and an outer connector housing. In use, the cable connector securely fastens or splices together at least two cables or cable sections and in electrical communication while also providing fluid communication therebetween. The cable connector further protects, and preferably seals off, the connection interface between the cables or cable sections and from the environment.

Embodiments of a fluid storage and introduction device 20 constructed in accordance with aspects of the present invention are provided. One embodiment of the device 20 includes an inner assembly 24 and an outer housing 26. When assembled, the device 20 is securely coupled to a cable or cable section 30 along a portion of its span. In use, the device 20 is capable of storing remediation fluid and introducing such fluid into the cable or cable section 30.
摘要:
A valve assembly configured to close off the flow of fluid within a fluid injection assembly includes a fluid column having a first open end and a second open end. A fluid flow path is defined between the first and second open ends of the fluid column, and a saturation valve portion is disposed within the fluid flow path. The saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path.
摘要:
A cable connection assembly for coupling a cable to an apparatus. The cable connection assembly may include a main body defining an inner cavity adapted to receive a pressurized fluid and receive at least a portion of the cable. The cable connection assembly may also include an attachment mechanism adapted to couple the main body to the cable and a seal assembly adapted to sealingly couple the main body to the apparatus. The cable connection assembly may also include an inlet port passing through the main body for permitting the pressurized fluid to be injected into the inner cavity.
摘要:
A cable connection assembly (100, 200, or 300) for coupling a cable (102, 104, 204, 302, or 304) to an apparatus (106, 206, or 306). The cable connection assembly includes a collar (108, 110, 210, 308, or 310) adapted to sealingly engage the apparatus, the collar having a fastener (144) for coupling the collar to the cable by rotating the collar into locking engagement with at least a portion of the cable.
摘要:
Cable terminations, junctions, or connectors having a cable affixed therein are provided, which include an internal cavity that is capable of (1) holding a selected volume of remediation fluid and (2) supplying it to the cable. Several embodiments of the cavity are capable of holding the remediation fluid under pressure for prolonged periods of time and through various environmental conditions such as temperature, moisture and sun exposure. Several embodiments of the internal cavity are divided into two or more chambers that are in physical communication through the opposition of pressure but which are chemically isolated. In several embodiments, an actuation device, such as a spring or compressed gas, pressurizes the fluid. Throughout the embodiments, individual access port(s) provide controlled access to the various internal chambers.

摘要:
A method and apparatus are described to prevent the unwanted energizing of equipment not normally intended to be energized when delivering a fluid to an energized power cable. The method and apparatus relate to the installation of a fluid back-flow prevention device in the line or equipment carrying a fluid to the cable, and also providing a pressure relief device that may relieve excess pressure to prevent damaging equipment.
