本発明は、電カケーブルをノン・オフセットで布設する
方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for laying electric power cables without offset.
（従来技術とその問題点）。(Prior art and its problems).
従来、管路布設ケーブルの熱伸縮対策としては人孔内に
オフセット部を設け、このオフセットの曲率を変えるこ
とにより、ケーブルの伸出しを吸収している。Conventionally, as a measure against thermal expansion and contraction of cables installed in conduits, an offset portion is provided in the manhole, and the extension of the cable is absorbed by changing the curvature of this offset.
しかし、ケーブルが大サイズになり、人孔径間長が長く
なると、ケーブルの伸出し量が太きくなり、オフセット
も大きくなるので、長さ乙〜ｚＳｍの大きな人孔が必要
となる。However, as the cable becomes larger and the manhole span length becomes longer, the amount of extension of the cable becomes thicker and the offset becomes larger, so a large manhole with a length of zSm is required.
従来のオフセットの概要図は第１図に示すとおりで１は

ーブル管路、矢印ａ、ｂはケーブル伸出し方向である。A schematic diagram of the conventional offset is shown in Fig. 1, where 1 is the manhole, 2 is the connection part, 3 is the offset shape before the cable is extended, 4 is the offset shape after the cable is extended, 5 is the cable conduit, Arrows a and b indicate the direction of cable extension.
（発明の構成と実施例）
本発明の、電カケーブルのノン・オフセット布設方式は
、人孔内でケーブルはオフセットをとらずに直線布設し
、ケニブルの伸出しは基本的にケーブルの接続部内で行
うことを特徴としたものである。(Structure and Embodiments of the Invention) The non-offset installation method for electric power cables of the present invention is such that the cable is laid in a straight line without offset within the manhole, and the extension of the cable is basically within the connection part of the cable. It is characterized by the fact that it is carried out in
本方式の要部である接続部構造の実施例の一つを第２図
に示して説明する。One embodiment of the structure of the connecting portion, which is the main part of this method, is shown in FIG. 2 and will be described.
接続ｍｉｏに、ケーブル１１ 、１１’がパツキン１２
を経て導入され、導体１３ 、１３’はプラグイン・コ
ンダクト１４のように軸方向可動の形で接続し、ケーブ
ル１１．１１’自体が接続箱１０丙に伸出す方式である
。なお、接続部内の絶縁はガスあるいは油によって行う
。The cables 11 and 11' are connected to the connector 12.
The conductors 13 and 13' are connected in an axially movable manner like a plug-in conductor 14, and the cables 11 and 11' themselves extend into the junction box 10. Note that the insulation inside the connection part is performed using gas or oil.
第２図のような接続箱１０を使用することにより、人孔
１は第３図のような形態になり、オフセットは不要どな
る。By using the junction box 10 as shown in FIG. 2, the manhole 1 takes the form as shown in FIG. 3, and no offset is required.
この方法により、人孔の大きさは作業スペースのみを考
慮したものとすれば、長さ２〜５ｍまで縮小することが
可能となる。By this method, the size of the manhole can be reduced to a length of 2 to 5 m, considering only the work space.
（発明の効果）
本発明のノン・オフセット布設方式は、ケーブルの伸出
しは直線接続のま＼、特殊接続部内で吸収させるため、
オフセットが不要になることが大きな効果である。(Effects of the Invention) The non-offset installation method of the present invention absorbs the extension of the cable within the special connection part without connecting it in a straight line.
A major effect is that no offset is required.
