摘要： Potential hot spots, such as at joints, in buried power cable runs are cooled by juxtaposing coolant flow conduits adjacent the cable and providing thermally conductive bridging members between the conduits and the cable throughout the potential hot spots to provide local cooling directly at the hot spots. The bridging members are cast metal clamps with portions to attach to lugs formed on the metallic cable sheath at the hot spots and portions which embrace the cooling conduits. Copper strips are provided underlying the clamps and embracing the cable and the cooling conduits to enhance thermal transfer from the cable to the coolant, and, with the coolant conduits formed of copper pipe, electrical insulators are provided in the metallic cable sheath so as to define an electrically isolated section in the region of the potential hot spot which can be coupled thermally and electrically directly to the coolant conduits.

摘要： A stop or through joint for high voltage, oil filled electric cables having a central conductor with an oil duct, insulation around the cable conductor and a sheath around the insulation which is slightly spaced, at least in part, from the insulation. The bared conductor ends are electrically joined and are surrounded by insulation which does not have a deliberately added oil channel for supplying oil to the duct. The joint is surrounded by a conductive casing, and within the casing, the cable insulation and the space between the insulation and the sheath has oil under pressure supplied thereto so that with variations of the operating conditions which cause oil flow in the cables, oil flows through the cable insulation so as to maintain the necessary oil content of the cables. Also, a cable system with a plurality of such joints intermediate the terminal ends of the cable system.

摘要： A cable length of the type comprising a conductor, polymeric insulation 3 over the conductor, a semiconducting screen 4 over the polymeric insulation, a fault carrying screen 5 over the semiconducting screen, and a protective sheath 6 over the semiconducting screen has at least the leading end thereof partially prepared for jointing prior to laying of the cable. At the leading and or each end the cable is stripped back over successive increasing lengths 7, 8, 9 to its polymeric insulation 3, its semiconducting screen 4 and its fault carrying screen 5. A semiconducting sleeve 13 fits over the protective sheath 6, extends over the stripped lengths of fault carrying screen 5 and semiconducting screen 4 and abuts the end portion of the latter. A clamp 12 disposed within the sleeve 13 terminates the fault carrying screen 5 and a sleeve 19 of polymeric insulation is provided on the stripped length of polymeric insulation 3. The sleeves 13 and 19 have the same outside diameter and thus the cable end has a generally cylindrical form with an outside diameter such as the outside diameter of the cable. This facilitates laying of the cable when the end is the leading end and has to be pulled through a trench. The cable as partially prepared is wound on a drum.
