【発明の詳細な説明】
電力ケーブルのより線構造からなる素線絶縁導
体の絶縁被膜を、還元性の雰囲気（気体、液体）、
または皮膜除去用の水溶液に浸せきして、除去す
る場合がある。[Detailed description of the invention] The insulating coating of the stranded insulated conductor of a power cable is coated in a reducing atmosphere (gas, liquid),
Alternatively, it may be removed by immersing it in an aqueous solution for film removal.
この発明は、そのようなときに、皮膜除去用の
流体が、導体の素線間のすき間を通つて、ケーブ
ル部分にまで入つていかないようにするための、
導体素線間のシール方法に関するものである。 The present invention provides a method for preventing film removal fluid from entering the cable portion through the gaps between the conductor wires in such a case.
The present invention relates to a method of sealing between conductor wires.
従来技術
大サイズのより線導体の導体素線間をシールす
る場合、第１図のように、ケーブル導体１０の目
標とする部分に、容器１４を当て、素線１２の間
に、シール材１６を充填する方法が知られている
（特開昭56−35611）。なおそのときは、導体中央
部の素線間までシール材が到達するように、ドラ
イバ１８などで、素線間を笑わせながら（すき間
を設けながら）、行なうようにしている。Prior Art When sealing between the conductor strands of a large-sized stranded conductor, as shown in FIG. There is a known method of filling the liquid with chlorine (Japanese Unexamined Patent Publication No. 1983-35611). At this time, the sealing material is moved between the wires (while creating a gap) using a driver 18 or the like so that the sealing material reaches between the wires at the center of the conductor.
しかしこの方法では、シール材が、素線間のす
き間に生じる毛細管現象のために、導体１０の長
手方向に広がり、シール長Lbが、所定のシール
Laの、３〜４倍の長さになつてしまう。 However, in this method, the sealing material spreads in the longitudinal direction of the conductor 10 due to the capillary phenomenon that occurs in the gaps between the wires, and the sealing length Lb
It ends up being 3 to 4 times as long as La.
このようにシール材の広がつている部分は、皮
膜除去用の薬液に浸したとき、皮膜が薬液に接触
しないため、皮膜は除去されない。 When the part where the sealant spreads in this way is immersed in a chemical solution for film removal, the film does not come into contact with the chemical solution, so the film is not removed.
この発明は、以上のような欠点がなくて、より
確実にシールできる方法の提供を目的とするもの
である。 The object of the present invention is to provide a method that does not have the above-mentioned drawbacks and can seal more reliably.
発明の構成
第２図のように、シールしようとする部分のケ
ーブル導体１０に適当な治具をはめ、真空引きし
ながら、その部分にシール材１６を注入すること
を特徴とする。Structure of the Invention As shown in FIG. 2, the present invention is characterized in that a suitable jig is fitted to the cable conductor 10 at the portion to be sealed, and a sealing material 16 is injected into that portion while vacuuming.
その説明
まず、第２図のように、シール部分のケーブル
導体１０に、真空引き容器２０をはめこむ。Description First, as shown in FIG. 2, the vacuum container 20 is fitted into the cable conductor 10 in the sealed portion.
そして、容器２０の下側から、真空ポンプ２２
によつて真空引きしながら、上側の入口２４か
ら、液状シール材１６を注入する。 Then, from the bottom of the container 20, the vacuum pump 22
The liquid sealing material 16 is injected from the upper inlet 24 while evacuating the chamber.
シール材１６には、パラフイン、水密性コンパ
ウンド、液状ゴムなどで、常温で固化するを用い
る。 The sealing material 16 is made of paraffin, watertight compound, liquid rubber, or the like, which solidifies at room temperature.
真空引きの圧力は、毛細管圧力に打勝つもので
あればよいので、微圧でよい。 The pressure for evacuation may be a slight pressure as long as it overcomes the capillary pressure.
このようにすると、第３図ａのように、シール
長Lcは、前記の所定シール長Laとほとんど等し
くなり、長さ方向に余分なシール部分を作らない
ですむ。 In this way, as shown in FIG. 3a, the seal length Lc becomes almost equal to the predetermined seal length La, and there is no need to create an extra seal portion in the length direction.
同図のｂは、従来の場合のシール長Lbを並べ
て示したものである。 b in the same figure shows the seal length Lb in the conventional case side by side.
なお、以上の処置をした後、シール部分から先
を皮膜除去用の流体に浸せきして素線絶縁皮膜を
除去し、それから導体接続を行なうわけである
が、接続の際、上記のシール材１６をとり除く必
要はない。 After the above treatment, the wire insulation film is removed by immersing the end of the seal in a fluid for film removal, and then conductor connections are made. There is no need to remove it.
発明の効果
(1) 上記のようにシール長が短くできるので、導
体口出し長も短くなる。Effects of the invention (1) Since the seal length can be shortened as described above, the conductor lead length can also be shortened.
(2) 真空引きしながらシール材を注入するので、
シール材が素線間の小さな隙間まで、よく入
る。(2) Since the sealant is injected while vacuuming,
The sealant can easily fit into the small gaps between the wires.
(3) 大がかりな装置を必要としない。(3) Does not require large-scale equipment.
