Definitions
- the present invention relates to a protective sheath with respect to the radiation, in particular the electric field generated by electrical cables extending inside the sheath, for example of the ICTA or ICTL type.
- shielded cables are known which are used to transmit high-frequency telecommunications signals either by means of a copper conductor or by means of an optical fiber, etc.
- the shielding is generally carried out by means of a conductive wire braid which is separated from the conductive wire or optical fiber by an insulating plastic layer, and is externally surrounded by another layer of insulating plastic material.
- ICTA sheaths ICTL
- ICTL insulating plastic layer
- ICTL outer surface is smooth or annealed to give them flexibility while strengthening their resistance to crushing.
- These sheaths do not have shielding against radiation and in particular against electric fields.
- These protective sheaths receive several electrical cables, usually a neutral cable, a ground cable and a phase cable connected to the electrical distribution network whose frequency is usually 50 Hz.
- the cables are intended to electrically power various devices or electrical outlets.
- the object of the present invention is to overcome these disadvantages by creating a protective sheath with respect to the radiation, in particular the electric field, generated by electric cables of the above type.
- this sheath is characterized in that it comprises an outer layer of electrically insulating plastic material which covers a layer of electrically conductive material, the end of the sheath comprising removable connection means for connecting the layer of electrically conductive material to an electrical conductor intended to be connected to the earth, said sheath surrounding or being intended to surround at least one neutral cable, a ground cable and a phase cable connected to the electrical distribution network.
- the interposed middle layer of conductive material strongly attenuates outward radiation from the electric field generated by the cables extending inside the sheath.
- the conductor intended to be connected to the ground extends longitudinally between the conductive layer and an insulating inner layer.
- the conductive layer may be a conductive metal sheet extending annularly or helically between the outer insulating layer and the insulating inner layer.
- This conductive metal sheet may be aluminum foil, mumetal, etc.
- the layer of conductive material is a polymer loaded with conductive powder such as graphite. As a result, the different layers can be coextruded. Also preferably, the sheath is annealed externally and internally, which allows it to be bendable and easily scored to measure.
- FIG. 1 is a cross-sectional view of a first version of a radiation shield according to the invention
- FIG. 2 is a longitudinal view with broken lines of the sheath according to FIG. 1
- FIG. 3 is a schematic view in longitudinal section of a sheath according to the invention, annealed and composed of three layers
- FIG. 4 is a view similar to FIG. 3, the sheath having two layers; and its end comprising a connection clamp
- FIG. 5 is a view similar to FIG. 4, the sheath comprising 3 layers
- Figure 6 is a longitudinal sectional view of two sections of a two-layer sheath, connected by means of a sleeve
- Figure 7 is a view similar to Figure 6, the sheath having three layers.
- Figures 1 and 2 show a protective sheath with respect to radiation, including the electric field generated by electric cables 1, 2, 3 extending inside the sheath.
- the sheath comprises an outer layer 4 of electrically insulating plastic material, an intermediate layer 5 of electrically conductive material, an inner layer 6 of electrically insulating material, an electrical conductor 7 intended to be connected to the ground which is connected to the intermediate layer 5 in conductive material.
- This sheath surrounds or is intended to surround a neutral cable 1, a ground cable 2 and, at least, a phase 3 cable connected to the electrical distribution network whose frequency is usually 50 Hz.
- the conductor 7 intended to be connected to the ground is a bare conductive wire, for example copper. It extends longitudinally between the conductive intermediate layer 5 and the insulating inner layer 6.
- the conductive intermediate layer 5 may be a conductive metal sheet, such as an aluminum sheet extending annularly or helically between the insulating outer layer 4 and the insulating inner layer 6.
- the outer and inner insulating layers 4, 6 may be made of plastic of the same quality as conventional sheaths currently used in the building, such as polypropylene, polyethylene or PVC.
- the outer diameter of the sheath may vary according to the ranges currently available for conventional unprotected sheaths.
- the thickness of these layers 4, 6 is of the order of 0.1 mm
- the intermediate layer 5, when it consists of an aluminum foil, can be very thin: about 1/100 th of mm.
- the sheath above can be made in several steps: application on an insulating inner sheath of an aluminum foil and then application on it of an insulating outer layer.
- the sheath may also be made in a single step by overmolding or the like.
- the sheath could be slit in the direction of its length to allow or facilitate the placement of the cables according to the application in question.
- Figures 3 to 7 show preferred embodiments of the protective sheath according to the invention.
- the sheath comprises an outer layer 4 of electrically insulating plastic material which covers a layer 5 of electrically conductive material.
- the end of the sheath comprises (see Figures 4 and 5) removable connection means for connecting the layer 5 of electrically conductive material to an electrical conductor 7 to be connected to the earth.
- the conductive material layer 5 is made of conductive powder-loaded polymer, such as graphite. The polymer contains, for example, from 5 to 40% of graphite.
- the conductive powder-filled polymer layer 5 is between the insulating outer layer 4 and an insulating inner layer 6.
- the sheath is annealed externally and internally, which allows it to be rigid, flexible and easily scored in sections of desired length.
- the removable connection means for connecting the layer 5 of electrically conductive material to an electrical conductor 7 intended to be connected to the ground comprise a conductive clamp 8 connected to the electrical conductor 7 adapted to electrically pinching one end of the sheath wall.
- the ends of the clamp 8 comprise, for this purpose, latching beaks 8a that can hook to an outer ring and / or inside the sheath.
- the sheath is composed of two layers, one 4 being insulating and the other 5, conductive.
- the conductive clamp 8 is in direct contact with the layer 5 and thus establishes the electrical connection with the conductive layer 5.
- the conductive layer 5 is composed of three layers (see FIG.
- the clamp 8 further comprises sharp and pointed lugs 9, adapted to pierce the wall of the sheath for establishing an electrical connection with the conductive layer 5, thanks to the elastic bearing force exerted by the two branches of the clamp 8.
- a sleeve 10 is provided for connecting the ends of two duct sections.
- This sleeve 10 is adapted to engage on the ends of these two duct sections, and has on its inner surface retaining notches 11 engageable between two outer rings of each of the two duct sections.
- means are provided for establishing the electrical connection between the conductive layers 5 of the two sheath sections.
- the above-mentioned connecting means comprise a flexible conductor 12 interconnecting the conductive layers 5 of the two segments of sheath.
- the connecting sleeve 10 carries, in addition, on its inner surface sharp and pointed lugs 13, adapted for piercing the wall of each duct section to establish an electrical connection between the conductive layers 5 of the two duct sections.
- the sheath that has just been described has the following main advantages: - Thanks to its corrugated structure, the sheath is flexible, bendable and easily divisible to measure.
- the sheath is liquid tight, including water and milt concrete. It can thus be embedded in concrete.
- the preferred sheath according to FIGS. 3 to 7 can be produced economically, for example from polypropylene and by simultaneous coextrusion of several layers.
- the sleeve 10 shown in Figures 6 and 7, can easily connect two duct sections while ensuring continuity of the conductive layer. Furthermore, the end clamps 8 make it easy to connect the conductive layer of the sheath to a conductive wire intended to be connected to the ground.
