A conductor pull-out rod 6 is connected to the cable conductor 5 by means such as crimping, and an epoxy resin sleeve 7 is fitted over the reinforcing insulator 4 from the conductor pull-out rod 6, and a flange 8 is attached to the bottom of the sleeve 7.
The lower case 9 is connected by connecting with bolts 10, and the lower case 9 is formed to have a small diameter at the bottom.
The lower end of the sheath 2 is oil-tightly fixed to the sheath 2 by means of lead fittings 11, and an oil chamber 12 formed by the sealed packaging is filled with the same insulating oil as the insulating oil in the cable 1.

等の絶縁ガスを封入する組立作業が必要になるた
め、以下に示すような問題点がある。 By the way, the structure of the termination box as described above is as follows: the reinforcing insulator 4 is formed on site, the mantle tube 7 is inserted, the termination box is assembled with the lower case 9, high voltage shield 13 and packing 17, 18, and then the termination box is assembled. Since it is necessary to assemble the case 15 and fill the gas chamber 16 inside the case 15 with an insulating gas such as SF 6 gas, there are the following problems.
(1) ケーブルコアの外周に巻装される補強絶縁体
を包被し得る寸法に套管を形成する必要がある
ため、終端箱全体の形成が大型化する。(1) Since it is necessary to form the jacket tube to a size that can cover the reinforcing insulator wrapped around the outer periphery of the cable core, the overall size of the termination box becomes large.
(2) 終端箱において、油室内の絶縁油がガス室内

るシール機能の信頼性が低い。(2) In the terminal box, if the insulating oil in the oil chamber leaks into the gas in the gas chamber, or conversely, if the gas in the gas chamber leaks into the oil chamber, it will cause electrical breakdown, so it is certain that leakage will occur. However, in the conventional on-site assembly structure, there is a possibility that a sealing failure may occur in the packing 17 applied to the part where the conductor pull-out rod 6 penetrates the sleeve tube 7, and furthermore, due to an accident, this packing 1
If damage occurs to 7, the insulating gas and insulating oil will be mixed in, and the reliability of the sealing function against the insulating gas and insulating oil will be low.
(3) ケーブル終端箱の組立後、ケース１５を被

ものとなり不経済である。(4) Due to the enlargement of the end portion, the amount of materials used increases and assembly requires a large amount of work cost, making it expensive and uneconomical.
