Abstract:
There is disclosed a cable entry system comprising a length of pipe which is adapted to extend through a bore in a wall and to be connected to the rear of a socket on the inside of the wall and to be closed by a cap on the outside of the wall, said cap having an aperture therein through which a cable may pass.
Abstract:
A method of passing a cable through a wall (10, 12) comprises the steps of drilling a hole through a wall and inserting a tube (16) so that the tube projects from the wall at both sides of the wall. A head (22, 24) is then mounted on opposite ends of the tube to trap the tube so that the tube cannot move axially in the wall. The heads are formed so that they present no obstruction to the internal bore of the tube. Finally, a cable (26) is passed through the internal bore of the tube.
Abstract:
The invention relates to a leading-through system for cables for leading cables (22) through fire compartmentation walls in after-installations. According to the system an opening is made in the wall and the cable is led therethrough. According to the invention a module (10) is mounted in the wall, the module is mounted in place while the leading-through cables (21) are sealed and there is a system for locating the cables formed on the surface of the module. The invention also relates to module having, formed on its surface, a system for locating the cables (22) which is made up of a grid (11) or a figure of another kind or recesses (11) formed for the cables. The system for locating the cables can be disposed on both sides of the module.
Abstract:
A high-pressure leadthrough apparatus for leading conductors (1) into pressurized systems. The apparatus comprises a housing member (2), which contains a conductor duct (3) connected to the pressurized space and opening onto the surface of the housing member; a screw unit (5) which closes the duct and is provided with threadings and a hole (4) for the conductor; as well as a screw unit chamber (6) larger in diameter than the duct, into which chamber the screw unit can be tightly screwn. According to the invention, the screw unit (5) is formed of a structure combination comprising a threaded bolt (7) which can be screwed into the screw unit chamber (6); a slip plate (8) supported against the bottom of the bolt and reducing tensional friction; a top support plate (9) supported against the slip plate; a bottom support plate (11) resting against the bottom (14) of the screw unit chamber (6), the bottom (14) being perpendicular to the conductor duct (3); as well as sealing (10) provided in between the top and bottom support plates; all of which are provided with holes (4) essentially corresponding to the diameter of the employed conductor.
Abstract:
A prefabricated fire sealing lead-through body (1) for one or more conduits (32) through a wall, for example. The body comprises a casing (2) with elastic fire retardant foamed material (4) disposed therein, said material being kept in the casing and compressed transverse the longitudinal axis there to for sealingly surrounding the conduit or conduits. During casting the building element, one end of the casing is fastened to a fastening element (10) attached to a contiguous shuttering wall (7). The fastening element remains in the building element after the shuttering wall has been taken down.
Abstract:
A bulkhead mounting plate (1) for EMI filter units (2) formed along three of its edges into alternating fingers (3). The fingers can grip the inside and outside surfaces of an edge port or a notch in a box. The plate is shaped by a right angle bend (4) of a fourth edge and perforated with precision mounting holes appropriate to any specified application. Fingers (3) on the mounting plate are dimpled to concentrate spring pressure between them and the box to improve the efficiency of electrical contact of the filter to be mounted on the plate.
Abstract:
A gland assembly for enabling a plurality of cables and/or tubes to pass through a wall in a sealed manner comprises a hollow main gland body sealingly connectable directly or indirectly to the wall at an opening therein and extending generally transverse, in use, from the plane of the wall, from an inner end to an outer end; an inner disposed sleeve member and outer disposed sleeve located within the main gland body in line with each other between the inner and outer ends of the main gland body, the inner and outer sleeve members being at least partially closed ended at their inner and outer ends respectively; sealing material disposed within the two sleeve members; the assembly being capable of adjustment to a first disposition such that little or no force in the inner/outer direction is imposed upon the sleeve ends which are then in an aligned separated disposition; the main gland body, the two sleeve ends and the sealing material being capable of having cables and/or tubes passed therethrough between the outer and inner ends thereof when the sleeves are in an aligned separated disposition; and the assembly being capable of a further adjustment to a second disposition such that force in the inner/outer direction is imposed upon the sleeve ends so as to urge the sleeves together and exert pressure on the sealing material in the inner/outer direction whereby to provide a seal about cables and/or tubes passing therethrough.
Abstract:
The invention concerns an inlet, and a corresponding procedure, for carrying a conductor electrode (1) in galvanically insulated mode through a wall (2). As taught by the invention, the inlet comprises an inlet duct (3) of the same material as the wall, an insulator plug (5) of a material having a thermal expansion coefficient substantially equal to that of the inlet duct, and a conductor electrode of a material having a thermal expansion coefficient substantially equal to that of said insulator plug.
Abstract:
A transit, preferably for electric cables, comprising a plurality of cable transit elements (8, 12,13, 16, 17) which are included in a cable transit frame (7a), and which are so adapted that they embrace a plurality of cables (9, 14) extending through the cable transit, or plugs (10, 15) which define temporary closing of cable openings. In order to arrive at a transit comprising fewer components for thereby giving a more stable construction, a simpler mounting, a simpler remounting and fewer sealing surfaces, it is according to the invention suggested that the cable transit elements comprise a combination of uniterrupted plates (8, 13, 17) having recesses (8a, 13a, 17a) for the through-going of cables, as well as individual elements (12, 16) adapted to the respective recesses (8a, 13a, 17a) in the plate or plates (8, 13, 17). The alteration between the uniterrupted plates and the individual elements is preferably made such that the cables ''rest'' on the plates, whereas the individual elements embrace the cable and/or plugs at the upper side thereof. Such a cable transit renders a favourable method for the pulling of cables (9, 14), especially when most of or all of the uniterrupted plates (8, 13, 17) are put in position at first and thereby define guidings for the pulling, which thereby is not bound by a special sequence.
Abstract:
Tool for making holes in a fire-sealing lead-through including an elastic, fireproof, foamed material, which is kept in compression at right angles to the longitudinal axis of the holes therein. The tool has a hole-making bar portion (2), provided with teeth (9) formed and arranged for hole-making correctly suited to such compressed foamed material. Adjacent to the hole-making part (2), the tool also has tapering driving part (1).
