Description

Pipe or cable lead-through with alternating layers {A PIPE OR CABLE LEAD-THROUGH HAVING LAYERS OF ALTERNATING GEOMETRY}

The present invention relates to seals, lead-throughs and transitions for cables or pipes. In particular, the present invention relates to a part of a seal or transition part having a peelable sheet to fit the diameter of a cable or pipe to be received.

In the prior art, there are cable transitions and the like having a frame in which a plurality of modules for receiving cables, wires or pipes are disposed. The module consists of an elastic material, for example rubber or plastic, and thus can be compressed. It is common for the interior of the frame to accommodate a number of modules side by side in one or more rows with some kind of compression unit. The compression unit is arranged between the frame and the module in such a way that the compressible module is compressed around a cable, wire or pipe when the compression unit is inflated. For ease of explanation, the term "cable" is used mainly in this description, but this should be interpreted broadly, and those skilled in the art will understand that this expression also generally includes pipes or wires.

Other types of seals, cable transitions, pipe penetrations and the like are generally cylindrical in shape and are received in an opening in the wall or in a sleeve in the wall. To function in the desired manner, the seal must fit snugly within the opening or sleeve of the wall in which the seal is received and must be able to fit the actual mounting dimensions. The mounting dimensions are determined by the inner diameter of the sleeve or opening. The seal has a cylindrical compressible body, which is axially compressed between fittings at opposing ends of the compressible body. By axial compression, the cylindrical body expands radially inward and outward. Also, the received pipes or cables can have various outer diameters, and therefore the module must be able to fit a cable or pipe having various outer diameters.

The two types of seals or transitions described above are used in various environments, such as for cabinets, technical shelter, junction boxes and machines. They are used in a variety of industrial environments such as marine and land, as well as automotive, telecommunications, power generation and distribution. Seals or transitions must be sealed against fluids, gases, fires, rodents, termites, dust, moisture, etc., and may be used for cables, wiring for electricity, communications, computers, etc. It can accommodate pipes for gases or liquids.

Parts accommodating the two types of single cables and the like described above often have packs of peelable layers inside. The layers or sheets are peeled off one by one until the inner diameter of the part matches the outer diameter of the cable received in the part. The sheets are strongly adhered to each other enough to be glued to each other while the sheets are loosely adhered enough to release the sheets one or more at a time from the stack together.

The present invention provides a compressible module for a cable entry or pipe penetration for receiving one or more compressible modules each surrounding a cable or pipe, wherein the cable entry or pipe penetration is disposed directly in the frame, Or disposed directly in an opening through a wall or other structural compartment forming a wall or other compartment, the barrier being formed of one or more compression units and one or more modules in the aperture or frame, the compressible module being in the diameter of the cable or pipe Having at least one peelable layer to fit, the at least one peelable layer is arranged in an axial groove of the compressible module. The compressible module is characterized in that the cross-sectional shape of the axial grooves in the direction perpendicular to the axial direction is not circular. By using a non-circular groove with a strippable layer, it is possible to fit to the dimensions of the cable or pipe having a cross section that is not circular. Examples of cable cross-sections include, but are not limited to, rectangular shapes that are often useful for busbars.

The invention also relates to a sealing system comprising a compressible module described above or below.
