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).

Abstract: The present invention concerns a compression wedge of a lead-through system. The compression wedge comprises a number of wedge elements (1, 2, 3, 4). At least one of the wedge elements (1, 2, 3, 4) has a core (9, 10, 11, 12) of a harder material than an outer part surrounding the core (9, 10, 11, 12). The part surrounding the core (9, 10, 11, 12) is made of an elastic material. The wedge is moved between a non-compression state and a compression state by means of one single screw (6) co-operating with a socket (7).

Abstract: The present invention concerns a module (1) of a seal or transition for cables or wires, which module (1) is to be placed inside a frame (10) together with one or more compression units (12). The module (1) comprises two module halves (2). Each module half comprises an outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The outer part has a straight section (3?) and two end sections (3?) at the ends of the straight section and placed perpendicular to the straight section, giving a U-form in end view. An inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) is placed in a recess (4) formed between the end sections of the outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) has a number of layers (6).

Abstract: The present invention concerns an indication means using the positions of two mutually moveable parts of an element. In one embodiment the indication means is used for a compression wedge of a lead-through system. The wedge comprises a first and a second wedge element (1, 2) moveable towards and away from each other between two extremes. 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 disclosure concerns a compression unit, in the form of wedge, of a transition for cables, pipes or wires. The wedge is to be placed inside a frame together with a number of compressible modules, which modules are to receive cables etc. The wedge comprises a number of wedge elements. The wedge is moved between non activated and activated positions by means of a screw, received in a through opening of a first wedge element, and a sleeve, received in an opening of a second wedge element. The wedge further comprises at least one clip, of an electrically conductive material, placed inside the wedge. The at least one clip is placed to connect the screw with the frame to connect the screw to earth.

Abstract: A seal, lead-through or transit for cables, wires or pipes which seal, lead-through or transit has one or more compressible parts surrounding the cable, etc. and a position of an opening receiving the cable, etc. is adjustable. In one example, the opening may be placed off-center on a partition line between two module parts. In other example, an inner compressible body may be placed inside an outer compressible body or between two module parts. The inner compressible body has an opening receiving the cable, etc. which opening is placed off-center. By rotating the inner compressible body the position of the opening receiving a cable, etc. is adjusted.

Abstract: A modular connector for cables and pipes has a compressible body with an axial groove provided therein for arrangement of a shielded cable extending from a first end to a second end, and the groove is dimensioned or dimensionable to sealingly fit around a circumference of the shielded or armored cable or the pipe. The connector has a conductor arrangement arranged between the first end and the second end, the conductor arrangement may be sandwiched between the compressible body and a cable screen or armor of the cable or the pipe. The the conductor arrangement further extends to an outside of the modular connector.
