［産業上の利用分野］
本発明は防錆処理を施した波付鋼管がい装ケーブルに関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a corrugated steel pipe armored cable that has been subjected to anti-corrosion treatment.
［従来の技術］
従来、波付鋼管がい装を有するケーブルにおいては、鋼

い状態をつくり出すことにある。[Prior Art] Conventionally, in a cable having a corrugated steel pipe armor, an organic or inorganic paint (typically an asphalt-based paint) is applied to the surface of the steel pipe. The purpose of applying this kind of paint is to prevent moisture from penetrating the anti-corrosion layer on the steel pipe, to prevent corrosive substances from entering under the coating due to damage to the anti-corrosion layer, or to prevent corrosion at the interface between the heavy layer and the metal base. The goal is to create a situation in which it is difficult for the disease to progress.
［発明が解決しようとする課題］
しかしながら、上記した従来技術には次のような問題点
があった。[Problems to be Solved by the Invention] However, the above-described conventional technology has the following problems.
（１）アスファルトの軟化点は低いので、ケーブル端が
下向きに配線される場合、周囲温度が高くなるとアスフ
ァルトが流れ出し、ケーブル端末部更には床面を汚染す
ることがある。(1) Asphalt has a low softening point, so if the cable end is routed downward, the asphalt may flow out when the ambient temperature rises and contaminate the cable end and even the floor surface.
（２）一般にこの種のケーブルの防食層はポリ塩化ビニ
ル（ＰＶＣ）から成るが、ＰＶＣ中の可塑剤がアスファ
ルト中に移行し、ＰＶＣの硬化・クラックを拾く場合が
ある。(2) Generally, the anti-corrosion layer of this type of cable is made of polyvinyl chloride (PVC), but the plasticizer in the PVC may migrate into the asphalt and pick up the hardening and cracks of the PVC.
本発明の目的は、前記した従来技術の欠点を解消した波
付鋼管がい装ケーブルを提供しようとするものである。An object of the present invention is to provide a corrugated steel pipe armored cable that eliminates the drawbacks of the prior art described above.
［課題を解決するための手段及び作用］上記目的を達成

ＶＣ防食層の硬化・クラックを防止したものである。[Means and effects for solving the problem] In order to achieve the above object, in the present invention, the surface of the corrugated steel pipe is coated with atactic polypropylene added with a rust preventive agent instead of the above asphalt-based paint. This prevents the anti-corrosion paint from flowing out from the cable end and prevents P.
This prevents the VC anticorrosion layer from hardening and cracking.

より、腐食が進行しにくい状態を作りだすことを意図し
たためである。In the present invention, the reason why a rust preventive agent is added to the acoustic polypropylene is to prevent the formation of fine pores in the coating film of the acoustic polypropylene, making it easy for corrosive substances to enter. This is because the intention was to create a state in which corrosion would be less likely to progress by adding a rust preventive agent to the active polypropylene in advance as a countermeasure.
