    • The invention relates to a fluid-tight cable duct (1) which is used to guide a cable (2) into a chamber (3) which can be impinged upon by pressure, and which comprises a housing (4), at least one cable (2) and one first and one second seal (5a, 5b) which can be pressure-loaded. The two pressure-loaded seals (5a, 5b) and the housing (4) define an inner hollow chamber (4d), and the cable (2) enters into the inner hollow chamber (4d) via the first seal (5a), through which the inner hollow chamber (4d) extends, and exits the inner hollow chamber (4d) via the second seal (5b). The inner hollow chamber (4d) comprises a pressure discharge opening (4c) which leads into an outer chamber (6) which is located outside the chamber (3) which can be impinged upon by pressure.
    • 本发明涉及一种流体密封的电缆管道(1),其用于将电缆(2)引导到可被压力撞击的腔室(3)中,并且其包括壳体(4),至少一个电缆 (2)和可以被加压的一个第一和第二密封件(5a,5b)。 两个加压密封件(5a,5b)和壳体(4)限定内部中空室(4d),并且电缆(2)经由第一密封件(4d)进入内部中空室(4d) 5a),内部中空室(4d)穿过其延伸,并经由第二密封件(5b)离开内部中空室(4d)。 内部中空室(4d)包括压力释放开口(4c),其通向位于室(3)外部的外部腔室(6),外部腔室可以通过压力撞击。
