Abstract

1,168,223. Electric cables. FELTEN & GUILLEAUME CARLSWERK A.G. 22 Jan., 1968 [23 March, 1967], No. 3228/68. Heading H1A. An electrical power cable comprises insulating strips 1 and core 2 with central channel 3 containing an insulating gas, for example a halogenated hydrocarbon, a hydrogen-free and chlorine-free hydrocarbon derivative or sulphur hexafluoride, under sufficient pressure to be liquid at atmospheric temperature and at the operating temperature. Other embodiments include multi-core cables with spacings (4), (Fig. 2, not shown), between the insulating sheaths of the cores filled with liquid; and helical supports or spacing discs providing spaces for liquid between the core 2 and the sheath (5), (Fig. 3, not shown).
