【発明の詳細な説明】 〔発明の背景と目的〕 本発明は、酸カケーブルの改良に関するものである。[Detailed description of the invention] [Background and purpose of the invention] The present invention relates to improvements in acid cables.

湿性で作業し易く経済的であるなどの理由から用いられ
ている。In the L4 cable, a large number of insulated wire cores are twisted together and an outer shielding layer made of metal tape is provided around the outer periphery.
In order to prevent the formation of a continuous cylindrical shape or to prevent the shape from collapsing, there is a fee to fill the insulated wire core with inclusions.As the inclusions, polypropylene is non-hygroscopic, easy to work with, and economical. It is used for the following reasons.
しかし、このポリプロピレンは、その分子構造がきわめ

ているもあの、金属テープ等と接触して長時間寿命保証
ができる程高度に安定化されたものではない。However, it has been recognized that the molecular structure of polypropylene is extremely susceptible to oxidation, and that its deterioration is significantly accelerated by contact with metals such as copper and iron. Moreover, the temperature of electric cables increases due to energization, and
It is required to have a long life of about 20 years, and the inclusions used must be extremely stable to be used. Despite this, the polypropylene currently used for interpositions has sufficient longevity for processing and applications at temperatures around room temperature, but it is highly advanced enough to guarantee a long life when in contact with metal tapes, etc. It has not been stabilized.
本発明は上記の状況に鑑みなされたものであり、長期間
の使用に耐えるポリプロピレンが充填された亀カケーブ
ルを提供する、ことを目的としたものである。The present invention was made in view of the above situation, and an object of the present invention is to provide a hexagonal cable filled with polypropylene that can withstand long-term use.

れているものである。The electric power cable of the present invention has a plurality of insulated wire cores twisted together, and the insulated wire core shape after the twisting is formed into a continuous cylindrical shape, or a polypropylene surround is formed to prevent the shape from deforming. It is filled with inclusions, and a shielding layer made of a metal tape is formed as the outermost layer, and the surface of the metal tape is treated with the polypropylene deterioration inhibitor.

に効果が認められる。Examples of the anti-deterioration agent include phenols, sulfur-containing esters, sulfur-containing ethers, phosphites, mercaptans, and sulfide amine compounds. In addition, triazoles, tetrazoles, substituted hydrazines, malonic amides, monomer acids, etc., which are said to be effective metal damage inhibitors or metal inert materials for polypropylene, have the effect of so-called antioxidants and metal damage inhibitors. Particularly preferred is the combined use of substances that have a preventive effect. The amount is not particularly limited, and even a small amount of these things attached to the surface is sufficient to produce an effect.

理した。Example 1 A test piece (not shown) had three insulated wire cores twisted together,
Filled with polypropylene split yarn inclusions,
A shielding layer of copper tape for external shielding is formed on the outermost layer. This copper tape is made of tetrakis(methylene 6,5-di-t-butyl-4-hydroxyhydronnamate)
0.2 parts by weight of methane, 0.2 parts by weight of tetrakis(methylenedodecylthiogropionate)methane as antioxidants, and 0.2 parts by weight of inphthalic acid a phenoxy-7 probionyl dihydrazide as a metal damage inhibitor. The surface was treated with a deterioration inhibitor dispersed and dissolved in 100 parts by weight of the vinyl paint.

レン介在物の劣化するまでの日数をめたところ、７日間
劣化は見られなかった。A cable with a length of 50 yen produced in this way was left open at both ends in a constant temperature bath at 120°C, and when the number of days until the polypropylene inclusions deteriorated was determined, no deterioration was observed for 7 days. .

に劣化し粉本化した。Comparative Example 1 A copper tape forming the shielding layer of a cable with the same structure as the above example was tested under the same conditions as the above example, and was brought into contact with the metal tape at 120°C for 1 day. The polyethylene inclusions in the exposed areas deteriorated to a brown color and turned into powder.
そして、１２０℃−２日では全体が褐色に劣化した。Then, after 2 days at 120°C, the entire product deteriorated to brown.
