Abstract
1483052 Electric cables PIRELLI GENERAL CABLE WORKS Ltd 9 Aug 1974 [17 Aug 1973 28 March 1974 21 May 1974] 39060/73 13862/74 and 22670/74 Heading H1A [Also in Division H2] An electric cable comprises at least one conductor insulated by lapped paper tapes, the cable being enclosed by a tubular sheath. A stable, homogeneous insulating liquid over the range - 10‹ to 85‹ C. at atmospheric pressure fills the cable and consists of, or includes as fire retardant at least one aliphatic halocarbon containing 2-4 carbon atoms per molecule, e.g. perchloroethylene, pentachloroethane, hexachlorobutadiene. If a solvent is present this may be an alkylbenzene oil for example. A known insulating liquid may be inserted in the cable during assembly, the toxic fire retardant being added to or substituted for that liquid later, e.g. after laying. A stop or straight joint, a sealing end or an oil pressure tank when used with the cable may also be filled with the insulating liquid.
