Abstract

1,124,081. Cable systems. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 11 Feb., 1966 [25 Feb., 1965], No. 8115/65. Heading H2C. [Also in Division H2] Underground high voltage cables consist of at least one conductor spaced from a sheath with a cooling gas flowing axially in the space between the two, so that part of the heat generated in the cable is conducted away from the cable by heat sinks, which are natural such as ponds; or artificial such as radiators. The gas may be nitrogen or a 3 : 1 mixture of sulphur hexafluoride and nitrogen. As shown, the cable has a non-magnetic pressure-tight sheath 1 in which a conductor 2 is supported by polyethylene spiders 3. The conductor is coated with polythene 4 to improve its impulse resistance. The coating may be metallized adjacent the conductor so as to minimize voids. A similar coating may line the sheath. The system is provided (Fig. 2, not shown) with spaced pumping stations, blocking members (7) being provided to stop the pump from feeding back to itself, and the pumping stations may incorporate filters and radiators.
