摘要： A way to evacute all moisture and air and then pressurize with SF6 gas (7), a cable and conduit (6) system used for electrical power distribution and transmission lines, by fabricating a termination at each end with a hole (9) slightly larger than the conductor (6) and providing a seal around the hole to the conduit. For a single phase cable, one electrical terminal (17) is sealed as it goes through the first end plate (8) and is connected to the neutral conductor (5). A second electrical terminal (23) is sealed as it goes through a second end plate (19) and is connected to the conductor (1). An enlarged conduit (32) is spaced between these two end plates (8 and 19) and is sealed to the two end plates. A tire valve (12) is installed in one end plate. A hole (36) to fit a pipe nipple is made at the top of the enlarged conduit (32) of one termination. A vacuum pump is connected to a pipe nipple screwed into the hole (36) and the termination evacuated. SF6 gas (7) is then let through the tire valve (12) until a pressure of 1 psig is reached, then shut off. The vacuum pump and nipple (20)are removed, then a patch (37) is sealed over the hole (36). SF6 gas (7) is now let to pressurize at 20-80 psig. Various numbers, sizes and kinds of conductors can be used in a conduit to make various kinds of high voltage power cables.

摘要： A gas-filled cable having low heat emission and low power loss and being used for the transmission of high-voltage electric current. The cable includes one or more conductors (14) which are axially spaced in position relative to each other in the cable by means of supporting insulators (16) inside an enclosing conduit (10, 12 or 12') which is filled with a insulating gaseous medium. In such a cable the conduit comprises on one hand a cylindrical metal sheath (10) of plain or low-alloy merchant steel having a carbon content of less than 0.6% and on the other hand a metal shield (12; 12') of non-magnetic material fixed inside the sheath and having a low specific electrical resistivity. Said metal shield (12') may be spaced from the metal sheath (10) along part of the inside of said sheath. Then said shield is perforated (at 22) by holes, slots or the like leading to the space forming a so-called particle trap (20).
