ルの接続方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for connecting a power cable in which a small (λ) coating layer is applied to a cable core in which at least a portion of the insulating layer is made of polyolefin.

鉛被覆層を鉛工又は溶接により接続することが多い。(Prior art and problems to be solved) Electric cables that generally have a lead coating layer, such as OF cables,
When connecting a one-paper insulated solid cable or a cross-linked polyethylene insulated cable, the metal case of the connection part and the lead coating layer of the cable are often connected by lead work or welding.

とがあった。However, OF cables and solid cables that use insulating tape made of polyolefin materials such as polyethylene or polypropylene, or composite tapes laminated with polyolefin film and insulating paper for part or all of the insulating layer, suffer from the heat of lead work or welding. This could cause damage to the insulation layer.

った。For this reason, connecting the lead coating layer of the power cable as mentioned above requires special lead work, such as using low-temperature solder or, in the case of OF cables, applying insulating oil and performing lead work while cooling. was doing the method. Alternatively, the outer layer of the insulating layer, which is affected by lead heat, such as 3 to 61, is wrapped with a tape that is not affected by lead heat, such as kraft paper or fluororesin tape, but either method is electrically or economically preferable. It wasn't something.

続部の信頼性に欠けるという問題点がある。Also, a lead-free method using a backing instead of lead or welded connections can be considered, but with this method, the backing leaks and securing the source current path becomes unstable with only a contact connection, and the connection lacks reliability. There is a problem.

The purpose is to expand the section to create a gap between it and the cable core, and connect it to the connecting metal case using lead work or welding at this section.

。For connection, first expand the end (2α) of the lead coating layer (2) to create a sufficient gap between it and the cable core (1). Insert the end (3α) of the connecting metal case (3) into the white part of the expanded lead coating layer end (2^), and use the ordinary leadwork part 11 to attach the leadwork (4). ) or make a welded connection. At this time, in the case of Solind cable, a water-cooled pipe (5) is placed along the cable core (1) and placed under the shipwrecking section, and cooling water is flowed through this to enter the inside of the leadwork section from the above gap. The outer surface of the cable core (1) may be connected by lead work or welding while cooling, or in the case of an OF cable, in addition to the cooling water pipe, lead work may be performed while flowing insulating oil from the oil passage in the cable core (1). Alternatively, the connection may be made by welding.
