Gas- eller luftisolerad elektriks anordning innefattande en bärare med låg dielektricitetskonstant för en ledare

摘要

A gas or air insulated electric device with a conductor (1) held spaced apart from a neighbouring conductive body (5), such as a structural element or an enclosure, by a support member (3) and surrounded by a gaseous insulating medium. The conductor (1) is at least partly covered by an electrically insulating coating (2). The support member (3) comprises an electrically insulating porous material with a solids' content of 30 % by volume or less and a relative dielectric constant of 1.5 or less.
