Field of the Invention The present invention relates to an oil stop processing method for a cable end and an oil stop processing kit used for oil stop processing for a cable end. The present invention also relates to a kit for oil stop treatment used for oil stop treatment of a cable end.

道路工事等において、Ｈケーブル、ＳＬケーブル、ベルトケーブル等の絶縁油を含浸した絶縁紙により導体被覆がなされたケーブルが露出し、工事の支障となることがある。   In road construction or the like, a cable covered with an insulating paper impregnated with an insulating oil such as an H cable, an SL cable, or a belt cable may be exposed, which may hinder the construction.

従来、このような場合において、支障となる部分のケーブルを切断除去した後、ケーブル残置部の端末には鉛工処理を施して油止の処理を行っていた。   Conventionally, in such a case, after cutting off and removing the cable that becomes a hindrance, the end of the cable remaining portion has been subjected to a lead processing to perform an oil stop treatment.

図４は、従来のケーブル端末の油止処理の処理フローを示す図である。また、図５は、絶縁油を含浸した絶縁紙により導体被覆がなされたケーブルの一例を断面図で示し、図５（ａ）はＨケーブルの断面図、図５（ｂ）はＳＬケーブルの断面図を示す。   FIG. 4 is a diagram showing a processing flow of oil stop processing of a conventional cable terminal. FIG. 5 is a cross-sectional view showing an example of a cable coated with an insulating paper impregnated with insulating oil. FIG. 5A is a cross-sectional view of the H cable, and FIG. 5B is a cross-sectional view of the SL cable. The figure is shown.

Ｈケーブル（ここではＨＰＬＺＮ）１００は、円形、扇形（図５（ａ））、又は卵形の導体１０１の上に絶縁紙（線心絶縁１０２）を巻き、その上に金属遮蔽テープ（しゃへい層１０３）を巻き、３心をより合わせて介在ジュート１０８を入れて円形に仕上げ、その上に金属帯（銅線織込布帯１０４）を巻いた後、乾燥浸油して、鉛被１０５を施し、さらにクロロプレン１０６、クロロプレンフリクション帆布１０７を施してなる。   The H cable (here, HPLZN) 100 is formed by winding an insulating paper (wire core insulation 102) on a circular, fan-shaped (FIG. 5A) or oval conductor 101, and a metal shielding tape (shielding layer) thereon. 103), three interstices are put together, interposing jute 108 is put into a circular finish, a metal band (copper wire woven cloth band 104) is wound on it, and then dried and immersed in oil. Further, chloroprene 106 and chloroprene friction canvas 107 are applied.

ＳＬケーブル（ここではＳＬＮ）２００は、導体２０１の上に絶縁紙２０２を巻いた後、鉛被２０３とクロロプレン引布帯２０４を施した単心鉛被ケーブル３条を、介在ジュート２０５とともに合せて円形に仕上げ、クロロプレン引布帯２０６とクロロプレンシース２０７を施し、さらにこの上にクロロプレンフリクション帆布２０８を施してなる。   The SL cable (here, SLN) 200 is formed by winding an insulating paper 202 on a conductor 201, and then combining three cores of lead-coated cable with a lead sheath 203 and a chloroprene-clothing strip 204 together with an interposing jute 205.

以上の工程ａ〜ｆにより、鉛被ケーブル１の切断端部１Ａと鉛製キャップ２の開口側端部２Ａとが融着ハンダ４Ｂにより水密に接合される。   Through the above steps a to f, the cut end portion 1A of the lead cable 1 and the opening side end portion 2A of the lead cap 2 are joined in a watertight manner by the fusion solder 4B.

（テープの巻回工程（工程ｇ））
テープの巻回工程（工程ｇ）では、上記接合工程（工程ｆ）の後、鉛製キャップ２と鉛被ケーブル１に跨って自己融着テープ５を巻回する。 (Tape winding process (process g))
In the tape winding step (step g), after the joining step (step f), the self-bonding tape 5 is wound across the lead cap 2 and the lead-covered cable 1.

自己融着テープ５の巻回は、自己融着テープ５を伸ばしながらテープ幅の半幅程度ずつずらしながら、螺旋巻回することにより行なう。自己融着テープ５は、例えば、自着性に富むブチルゴムからなる。   The self-adhesive tape 5 is wound by spirally winding the self-adhesive tape 5 while shifting the self-adhesive tape 5 by about a half width of the tape width. The self-bonding tape 5 is made of, for example, butyl rubber having a high self-adhesive property.

自己融着テープ５を巻回した後、さらに、鉛製キャップ２と鉛被ケーブル１に跨って耐候性に優れた保護テープとしてビニルテープ６を螺旋巻回して保護層を形成してもよい。   After winding the self-bonding tape 5, the protective layer may be formed by spirally winding the vinyl tape 6 as a protective tape having excellent weather resistance across the lead cap 2 and the lead covered cable 1.

以上、ＳＬケーブルの場合を例に説明したが、Ｈケーブルやベルトケーブル等にも同様に適用できる。   The case of the SL cable has been described above as an example, but the present invention can be similarly applied to an H cable, a belt cable, and the like.
