Abstract: The present invention concerns a transit for leading cables, pipes or wires through a partition in a sealed way. The transit comprises a sleeve (1) and a seal (2) to be received inside a central through opening of the sleeve (1). The seal (2) comprises a base part (7), a front fitting (9) and a rear fitting (10), which front and rear fittings (9, 10) are placed at opposite ends of the base part (7). The base part (7) of the seal (2) is made of a compressible material, whereby the front and rear fittings (9, 10) are arranged to be moved towards each other in order to compress the base part (7) of the seal (2). The compression is achieved by co-operating threaded pins (19) and nuts (11). At least one rotating fitting (13) is placed between the front fitting (9) and the base part (7) of the seal (2), and is received on one of the threaded pins (19).

Abstract: The present invention concerns a wedge for a lead-through system. The wedge comprises a first wedge element, a second wedge element, a third wedge element and a fourth wedge element. The first and second wedge elements are arranged moveable towards and away from each other. The third and fourth wedge elements are placed on opposite sides of the first and second wedge elements, abutting the first and second wedge elements along sloping surfaces. The wedge elements and the sloping surfaces are so arranged that the third and fourth wedge elements will be moved away from each other when the first and second wedge elements are moved toward each other and that the third and fourth wedge elements are moved toward each other when the first and second wedge elements are moved away from each other. The wedge further comprises a bracket on the outside of the first wedge element. The bracket receives a socket arranged to be able to rotate in relation to the bracket.

Abstract: The present invention concerns a seal comprising a front fitting (1, 21, 41), a rear fitting (2, 22, 42) and a compressible part (3, 23, 43). The compressible part (3, 23, 43) is placed between the front fitting (1, 21, 41) and the rear fitting (2, 22, 42). The seal is a transition for a conduit through a wall (16), wherein the conduit is received in a central through opening of the seal and wherein the seal is received in an opening of the wall (16). In a mounted seal the compressible part (3, 23, 43) seals inwards against the conduit and outwards against an inner surface of the opening of the wall (16). The axial extension of the compressible part (3, 23, 43) is larger than the thickness of the wall (16) at the opening of the wall (16).

Abstract: Disclosed is a monitoring system (2) for cable, pipe or wire transits (1; 1a . . . 1n) of a type which has a plurality of transit elements (10, 20, 30, 40; 42; 400) to be assembled into a sealed installation of one or more cables (2), pipes or wires at a site (5). Each transit (1; 1a . . . 1n) has a transit guard unit (50; 50a-50n; 150; 250; 350; 450) configured to detect a condition indicative of whether the installation of the cables, pipes or wires in the transit is sealed or at least potentially not sealed. A central monitoring unit (70) is configured to receive, over a communication network (60; 60b), first information (110, 112) about the condition detected by the transit guard unit (50) of any of the transits (1a . . . 1n).

Abstract: The present invention concerns a compression wedge of a lead-through system. The wedge is moveable between two extremes and has distinct stops at the extremes. The distinct stops are given by co-operating stop edges (16, 17, 18, 23). In one embodiment two of the stop edges (16, 17) are provided on a screw (6). One end of the screw (6) is received inside a socket (7) fastened to a first wedge element (1). A second end of the screw (6) is fastened to a second wedge element (2). The socket (7) and screw (6) are mutually moveable in an axial direction of the screw (6). One stop edge (23) is provided in an inner opening (35) of the socket (7) and one stop edge (18) is provided in an opening of the first wedge element (1).

A socket (7) is fastened in a rotatable way to the first wedge element (1) and a screw (6) is fixed to the second wedge element (2). One coloured end (11) of the screw (6) is received in a through opening (17) of the socket (7). The inner surface of said through opening has another colour than the coloured end (11) of the screw (6). The mutual position of the first and second wedge elements (1, 2) are controlled by rotation of the socket (7) on the screw (6).

Abstract: The present invention concerns a wedge comprising four wedge elements (1, 2, 3, 4). A first wedge element (1) and a second wedge element (2) are arranged moveable towards and away from each other. A third wedge element (3) and a fourth wedge element (4) are placed on opposite sides of the first two wedge elements (1, 2) abutting the two first wedge elements (1, 2) along sloping surfaces. The third and fourth wedge elements (3, 4) will be moved away from each other when the first and second wedge elements (1, 2) are moved toward each other and will be free to move toward each other when the first and second wedge elements (1, 2) are moved away from each other. The movement is accomplished in that a first part (7) is fixed rotatable in the first wedge element (1) and that a second part (6, 40) is fixed non-rotatable in the second wedge element (2).
