Abstract

Изобретение относитс к электротехнике, а именно к соединению подводных кабелей св зи. Цель - повышение надежности путем повышени продольной герметичности. Способ осуществл етс следующим образом. Соедин ют жилы кабелей с контактным элементом 5, нанос т на него слой невулканизированной резины и отформовывают сросток. Затем на сростке размещают контакт 7 в виде трубчатого сетчатого элемента и сращивают его с экранами 4 кабелей, после чего на каждый сросток поверх контакта 7 нанос т дополнительный герметизирующий слой 10 электроизол ционной сырой резины защитный слой также из сырой резины. Нанесение герметизирующего и защитного слоев из невулканизированной резины позвол ет обеспечить просачивание резиновой смеси сквозь чейки трубчатого сетчатого элемента до взаимодействи со слоем изол ции на контактном элементе под действием давлени резиновой смеси, а затем в процессе вулканизации всего этого пакета образуетс единой монолит. 6 ил.The invention relates to electrical engineering, in particular to the connection of submarine communication cables. The goal is to increase reliability by increasing the longitudinal tightness. The method is carried out as follows. Connect the cores of the cables with the contact element 5, apply a layer of unvulcanized rubber on it and shape the splice. Then, contact 7 is placed on the splice as a tubular mesh element and spliced with shields of 4 cables, after which an additional sealing layer 10 of electrical insulating raw rubber is also applied to the splint from raw rubber on each splice. The application of a sealing and protective layer of unvulcanized rubber allows the rubber mixture to seep through the cells of the tubular mesh element before interacting with the insulation layer on the contact element under the pressure of the rubber mixture, and then a single monolith is formed during the vulcanization process. 6 Il.
