外被４と接触しThe present invention is an electric cable for transmitting high current under low voltage,
Especially welding ~ pull (cable de soudage)
). The invention also relates to first and second manufacturers of cables of this type. Cables carrying high currents at low voltages, in particular welding cables, usually consist of one or more conductors consisting of a plurality of basic strands, covered with a jacket. Cooling passages are provided between the jacket and the conductor or conductors, through which water necessary for cooling the cable circulates. However, as the cable is used more and more, the basic S1 lands begin to show wear due to electrodynamic vibrations and mechanical stresses that induce blockage of the cold JJl passages. The cables of this type contain a braid-like section of polyester or pyrene between one or more conductors and the jacket.
Therefore, the risk of cooling passage blockage is even higher. An object of the present invention is to significantly extend the life of the couple by reducing damage to the basic strands by increasing the protection of the conductor using a transparent envelope.7 Therefore, the present invention The invention relates to a couple of types including at least one multi-strand conductor and an outer sheath inside which water circulates, wherein at least one multi-strand conductor is covered with a transparent sheath allowing water circulation. The present invention provides electrical cables, especially welding cables, for transmitting strong currents at low voltages. Said transparent envelope is composed of two layers of at least one band fixed to each other. As an example, one layer may be composed of at least one spiral band, It consists of at least one longitudinal layer. Alternatively, both of these layers may be formed of a spiral band. The invention also relates to a method for manufacturing a cable of this type;
The manufacturing method consists of coating at least one multi-strand conductor with a jacket C' that allows water circulation;
One conductor before placing said jacket around two or more conductors.
It is characterized in that each material layer is placed separately in the center of an extruder, and two material layers are extruded thereon and fixed to each other. In this case, an inner die is used to extrude the inner layer, and an outer die is used to extrude the outer layer. 41 Advantageously, one layer is formed by a rotating inner die or a rotating outer die, and the other layer is formed by a fixed inner die or a rotating outer die. A second manufacturing method of the invention consists of covering one or more multi-strand conductors with a sheath that allows water circulation, said sheath being placed around the conductor. The conductor is introduced into an impregnating device or a hot bonding device before the conductor is heated, and then the monolithic wire constituting the second layer is arranged and fixed to the first layer. Advantageously, a rotating plate The first layer is wound on at least one winding machine placed above, and the second layer is arranged on at least one fixed or rotary winding machine and a die. Two types of electric cables of the present invention and the above-mentioned first and second electric cables will be explained as limited specific examples. A cable 1 is shown in which the jacket 3 consists of two mutually independent but fixed layers, the inner layer 5 in contact with the conductor 2, the outer layer 1 in contact with the jacket 4.

Neither the bands 6 nor the bands 8 touch each other between the cables themselves, in order to constitute a sheer envelope 3 so that water can circulate along the cable 1. Water comes into contact with conductor 2. A cable 10 is shown in FIG. 2 that includes three multi-strand conductors 12. As shown in FIG. These conductors are each covered with a jacket 13 identical to the jacket 3 of FIG. 1, and the three are placed together in a sealing jacket 14. The thrust ball bearing 39 is brought into contact with the thrust ball bearing 39 through this contact 41. This arm is motor 42
It is driven by a motor 42 via a toothed pulley 43 that connects the pinion 44 and the pinion 45 connected to the arm 37 by a threaded square portion 1tA46. This device thus includes a funnel 22, a central ih and a plurality of passages 50.
, i.e. between the central body 21 and the member 28, comprising a material supply circuit consisting of passages extending from said groove to the die assembly and distributed on the periphery. 4 and 5 show the fixed die 27 in more detail. This die is provided with a plurality of grooves 27', six vortices covering each longitudinal band of the outer layer 7 of the envelope 3 or 13. 6 and 7 show the rotating die 38 in detail. This chair also has a plurality of grooves 38゛, and the valley groove is covered with 38゛.
or corresponding to each spiral band 6 of the thirteen inner layers 5. Next, an example of an extrusion operation will be shown. First, the land conductor 2 or 12 is introduced into the hollow arm 37 and passed through the inner die 38. The die 38 and arm 37 are connected by a motor 42.
Rotate with . A thermoplastic material or elastomer is introduced into the funnel 22. This material flows into the channel 50 and is then extruded through both the inner and outer dies to cover the conductor 2 or 12 and form the open envelope 3 or 13. The inner die rotates to form a spiral band 6 of the inner layer 5, and the outer stationary die forms a longitudinal band 8 of the outer layer 7. Since the material is still in a molten state in the die section, both layers 5 and 7 are fixed naturally. The extruder can also be used with an outer die that rotates by known means to form the outer layer consisting of a spiral band. FIG. 8 shows a device 60 for forming a single wire 1185, an impregnation or hot bonding device, and a device 80 for forming a second layer 7 of four from a single wire. ing. The first layer forming device 60 is an I
,: Rotary play 1-61 in which the winding machine 62 is arranged diagonally
It consists of The winding machine 62 supports a reel 63 on which the wire rod 6 is wound. Rotate the wire 416 to the play 1 and move the conductor 2 in the longitudinal direction to connect the wire 416 to the conductor 2.
It is wound in an A spiral shape. However, in order to enable water circulation, a space is provided between the winding phases 7j, and this wire 6 is connected to the first layer 5.
Configure. Of course, it is also possible to form the first layer 5 made of a plurality of wire rods 6 very easily by arranging a plurality of winding machines on the plate. The conductor 2 with the first layer 5 then passes through the device 70 . This device may be a device such as a furnace or e'tuve using bot melts, adhesives or surface melts, etc. The second layer forming device 80 has eight turns @82 in this embodiment.
and one die 84. Although only two winding machines 82 are shown in the drawing, each of these winding machines 82 has a reel 83.
A wire material 8 is wound around these reels. The device 80 of FIG. 8 is of a fixed type, with wires 8 arranged longitudinally to form the second layer 7. This device 80 can of course also be placed on a rotating plate so that the wires of layer 7 are not arranged in a helical manner. These two layers 5 and 7 constitute the transparent envelope 3. The arrangement of the wire members is performed as follows, for example. The conductor 2 is moved in its axial direction and the first layer 5 is wound by the rotary play 1-61. The conductor 2 coated with the first layer 5 is passed through the device 70 and then the second layer 7 is passed longitudinally or spirally II. Attach the outer sheath to this to obtain a completed cable.
