摘要： High voltage electric cables of the kind having a laminated dielectric comprising lappings of insulating tape impregnated with an insulating liquid enclosed in a liquid-impervious sheath or pipe. Such laminated dielectric is most commonly built up from lappings of paper tape although proposals have been made to use plastics film along or interleaved with paper and it has been proposed that plastics film having on one or both sides an adherent layer of fibrous material should be used. More particularly the invention relates to such a cable in which the insulating liquid is a liquefied gas which, in addition to forming part of the dielectric, acts as a cooling medium thus increasing the cable rating for a given conductor cross-section.
