誘導加熱装置を設置せしめてなるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a rubber/plastic insulated cable, and more specifically, the present invention relates to a manufacturing apparatus for a rubber/plastic insulated cable, and more specifically, a device for manufacturing a rubber/plastic insulated cable. This is achieved by installing a cable conductor induction heating device.

来ていることは知るところである。It is known that in recent years, insulators of rubber/plastic insulated cables have become thicker and thicker as well as their voltage ratios have increased.

ある。On the other hand, this type of cable is made by extruding an insulator using an extruder and then crosslinking (or vulcanizing) the insulator using a crosslinking (or vulcanizing) tube. The above process now takes a long time. The object of the present invention is to provide a manufacturing device that makes it possible to install a work coil for induction heating of a cable conductor on the outside of a crosslinking (or vulcanization) cylinder.

い、その内部までの処理に長時間を要するためである。That is, the gist is that the cable conductor induction heating device is installed between the extruder and the crosslinking (or vulcanizing) tube or in a part of the crosslinking (or vulcanizing) tube. A non-metallic cylindrical body installed so that the cable core can pass through it, a work coil for heating the cable conductor installed outside the cylindrical body, and an insulator meat around the work coil outside the non-metallic cylindrical body. This is because as the thickness increases, it takes a long time to process the inside.

られた気体あるいは液体とより構成せしめた点にある。In view of this, it is possible to improve the processing efficiency by simultaneously using a work coil during the crosslinking (or vulcanization) treatment of the insulator and heating the cable conductor at the same time to heat the insulator from the inside and outside. Although this method has been proposed, it has structural problems because the work coil must be installed inside the crosslinking (or vulcanization) tube, and it has not yet been put into practical use. It consists of a pressure-resistant container installed in a sealed manner, and a gas or liquid filled in the pressure-resistant container at a pressure that is the same as or close to the pressure inside the crosslinking (or vulcanization) cylinder. At the point.

は無くするようにした。) or gas (for example, air nitrogen gas, carbon dioxide gas, sulfur hexafluoride gas, etc. are preferable) for the following reasons. In general, metals such as stainless steel are used for the crosslinking (or vulcanization) tube.In order to inductively heat the cable conductor using the work coil installed outside of the tube, it is necessary to at least For the inside, it is necessary to use a nonmetallic material with negligible electrical conductivity, such as ceramics, glass, or ceramics, instead of the metals mentioned above. However, since each of these materials is fragile, there are problems in simply using them as part of a crosslinked (or vulcanized) tube. Rather, it is no exaggeration to say that it is impossible to use this type of crosslinking (or vulcanization) cylinder in which a high-temperature and high-pressure atmosphere of, for example, 300 oo and 20 kg/g is created inside the cylinder. In view of this,
In the present invention, a non-metallic cylindrical body is used in place of the conventional metal cross-linked cylinder, a pressure-resistant vessel is provided on the outside of the cylinder, and a cross-linked cylinder is installed inside this pressure-resistant vessel. Bowl) The pressure difference applied to the non-metallic cylinder is reduced or eliminated by filling the cylinder with gas or liquid at a pressure that follows the pressure inside the cylinder.
