摘要： A method for enhancing the dielectric properties of an electrical cable having a central stranded conductor encased in a polymeric insulation. The cable defines an interstitial void space (v1) between the strands of the conductor. The volume (v2) of a dielectric enhancement fluid required to be absorbed by the cable to reach a predetermined level of dielectric enhancement is determined. The ratio of (v1/v2) is computed. If the ratio of (v1/v2) is greater than a maximum ratio of 1.4, then a quantity of the dielectric enhancement fluid is diluted with a sufficient quantity of a diluent to produce a mixture of diluent and dielectric enhancement fluid, such that when the volume (v1) of the mixture is supplied to the cable interior, the cable will have been supplied with a volume (v3) of the dielectric enhancement fluid within the mixture such that (v3/v2) is less than 1.4. The diluent is substantially insoluble in the polymeric insulation, has a sufficiently low initial viscosity to enable introduction into the cable interior, and is miscible with the dielectric enhancement fluid.

摘要： A method and apparatus for connecting flow-through cables (400, 402). Flow-through cables (400, 402) have a conduit or a plurality of conduits (412, 414) longitudinally placed inside the cable to allow fluid passage. Special terminators, joints, and methods for installing these devices are described herein. One method for connecting two flow-through cables involves: inserting a tubing material (410) into the conduit (412) of one flow-through cable (400), placing a crimp connector (420) over the cable's conductive core (404) and crimping the crimp connector. The tubing material (410) is then placed into the conduit (414) of the second flow-through cable (402), the cables are aligned, and then the crimp connector (420) is fastened to the conductive core (406) of the second flow-through cable (402). The termination assembly includes a rigid tubing material, a hollowed plug assembly that includes a single or a plurality of rigid tubes, a tubing connector connected to the single or plurality of rigid tubes, and a conductive terminator that has a cavity adapted to anchor a cable's conductive core and allow a flexible tubing material to attach to the single or plurality of rigid tubes while being routed through the conductive terminator.

摘要： A flow-through cable for transmitting information (20) is provided. The cable includes a jacket (22) having a length and an information conducting core (26) coaxially received within the jacket. A first insulation layer (24) surrounds the information conducting core and has a dieletric strength. The cable further inCludes a first conduit (28) disposed within the jacket. The first conduit is adapted to permit a compound to flow therethrough and is chemically permeable to permit at least a portion of the compound to diffuse through the first conduit.

摘要： A wire rope (10) includes a plurality of strands (12). The strands are formed from individual wires or filaments (14). The strands are wound about a central axis. A conduit (16) also extends along said central axis. The conduit has walls that are foraminous and permit radial flow of a lubricant. The lubricating compound is injected into the channel (18) defined by the conduit. The lubricating material migrates through the orifices in the conduit wall and radially outwardly therefrom.

摘要： The cable connector (2) of the present invention includes an interior connector and an injection fitting. The interior connector includes an elongate hollow electrically conductive conduit (2) having open ends (6, 7) adapted to receive the interior ends of the two sections of electrical cable. The interior connector also includes a fastener for securing the interior ends of the two sections of electrical cable in the open ends (6, 7) of the elongate hollow electrical conduit (2). Another component of the interior connector is a stress control tubing that is adapted to cover the elongate hollow electrically conductive conduit. An insulation sleeve (152) covers the stress control tubing (150). Compression rings (148) located on the insulation sleeve adjacent each of the open ends of the elongate hollow electrically conductive conduit (2). The interior connector also includes a metal wrap adapted to cover the insulation sleeve and the compression rings. An outer sheath (146) is adapted to cover the metal wrap to complete the assembly of the interior connector. The injection fitting includes a cable adaptor that is attachable to the outer surface of the electrical cable section (120) at a position remote from the exterior end of the electrical cable section to leave exposed a portion of the outer surface of the electrical cable section adjacent the exterior end thereof. The injection fitting also includes a sleeve (192) having a first end, second end and a fluid injection opening. The first end of the sleeve (192) is adapted to fit over the exposed portion of the outer surface of the electrical cable section adjacent the exterior end thereof. The second end is adapted to fit over a conductor contact attached to the central conductor portion of the electrical cable section.
