FIELD: electricity.SUBSTANCE: invention relates to the area of electric engineering and electrical power engineering, and more specifically to design of sealed entries; it may be used in different technical and process electrical installations and machines, for example at nuclear power plants. Modular sealed multilinear entry comprises a set of hollow metal sections A joined by two sections into a module by a metal tube with one or two terminated cables passing through it inside the module section with sealed current feedthroughs passing through bushing insulators reinforced with a common cartridge clamp and an opening for remote check-up of inner volume hermeticity and further passage of current feedthroughs covered by a thermally shrinkable tube, from module cartridges inside side conduits, which pass hermetically through intermediate bushes inside openings of entry flanges coupled in a sealed way with a covering tube filled with an element of biological shielding and protective housings, inside which from the side of "clean area" there are unions for remote hermeticity control in each modular entries.EFFECT: invention allows increase in reliability and expanded functionalities.6 cl, 6 dwg |
