Description

【発明の詳細な説明】 （産業上の利用分野） この発明は１通信ケーブル、光ケーブル、電カケープル
等を収容するケーブル収納用分割管路に関するもので、
その布設張力を軽減しようとするものである。
（従来の技術） 通信ケーブル、光ケーブル、電カケープルなどを布設す
るときに１図面に示すように管路ｌ内に数条の分割管路
２を配設し、その中にケーブル３を布設することが行わ
れている。この分割管路２を採用するやり方は管路ｌの
内径に比較してケーブルのそれが細い場合に管路ｌの有
効利用という観点から特に効果的である。
（この発明が解決しようとする問題点）しかしながら、
分割管路２の素材として一般にポリエチレンのようなプ
ラスチックを用いているために分割管路２内へのケーブ
ル布設時のケーブルとの摩擦係数が０．５〜０．６と比
較的大きいことから布設張力が大きくなりプーリングア
イのケーブル把持力から最長でも３００ｍ程度しかケー
ープルを布設することができない。
（問題点を解決するための手段） この発明は、以上の観点から分割管路を構成するプラス
チック内に滑剤を混入することにより、その摩擦係数を
低減せしめ、以ってその中へのケーブルの布設を古島に
したものである。
（実施例） 分割管路を構成するプラスチックとしてポリエチレンを
用い、その中に４種類の滑剤すなわちａ：エルシルアミ
ド、ｂニステアリン酸、Ｃ：ポリエチレンワックス、ｄ
：マイクロワックスを添加量（重量部）を変えて混入さ
せて直径３８ｍｍの分割管路を作り、その中に直径２２
ｍｍのポリエチレンシースされた光フアイバケーブルを
引入れたときの摩擦係数を測定したところ下表のごとく
であった。
表 表から明らかなように、滑剤としてエルシルアミドを０
．５重量部以上添加したものは、ケーブルとの摩擦も小
さく効果的であることがわかる。
また、その量は１．０重量部以上では摩擦係数に差異が
ないことから多くても１．０重量部添加すればよい、か
くして滑剤としてエルシルアミドを１．０重量部添加し
たポリエチレンからなる分割管路を採用することにより
ケーブルの布設条長を約６００ｍになすことができた。
（この発明の効果） この発明は以上のように１分割管路を構成するプラスチ
ック内に滑剤を添加することによりケーブルとの摩擦を
少くしたので、その内部へのケーブルの引入れを容易に
することができるという利点がある。
