Title: Screening of high voltage cables - by helical wrapping with screening tape folded to ensure a potential balance along each tape interface
IPC: H01B9/06
Filed: 1973-06-13
Abstract: Screening tapes comprising layers of insulating and semi-conducting materials respectively, to be laid up between the metal conductor core of a power cable and a combination of solid and liquid insulation surrounding the core where the lay-up pattern for the screening tapes comprises use of two such tapes with their semi-conducting faces towards the core, the first being laid with the edges of the tape being doubled over outwards, the second tape being overlaid on the first tape but offset in pitch and with its edges turned inwards to lie level with the edges of the lower tape. An independent winding of a semi conductor tape may be interposed between the conductors and the inner screening tape. The edge folds on each screen tape can be similar or different widths, should be > 1 mm wide but 1/2 the width of the tape as folded. Esp. appliable to cable operating at >=500 kV with the insulating layer of the screening tape made of a paper of controlled stretch structure, pref. of polyolefin fibres or film, and the semi conductive layer is made of similar material loaded with an electrically conductive filler such as a smoke black. The lay-up ensures that any interstitial spaces between the opposing faces of the screening tapes and/or other materials are bounded by materials at the same potential, viz either insulating layers or conductive layers. The gaps between the adjacent edges of the overlaid tapes are well sealed against penetration by conductive or insulating fluid, reducing the risk of dielectric cavitation.
