FIELD: arrangements for passing electric cables through walls of pressurized premises of nuclear power stations. SUBSTANCE: stuffing arrangement has case with hermetically sealed modules embedded in its ends and accommodating electric conductors connected to external circuit components installed in embedded part of wall or steel shell and sealed at ends of case; case wall under embedded part has hole and ends of case are double-wall structures whose inner walls are joined together by means of pipes and have holes in outer walls coaxial with pipes and having diameter smaller than inner diameter of pipes carrying modules inside them which are provided with sealed connector plugs at ends embedded in holes of outer walls; one of case ends carries pipe connections for communicating with device monitoring tightness of pipe interior and interpipe space; electric cable conductors are connected to removable terminals of connector receptacles. EFFECT: improved reliability, space-saving, convenience in servicing, repairability of stuffing arrangement due to monitoring tightness of separate basic parts of case, including embedded parts, introduction of sealed connectors. |
