A cable was produced by crosslinking.
第１図は、上記のようにして製造したケーブルの断面を
示すものであり、■は導体、２は絶縁体、３はシースで
ある。FIG. 1 shows a cross section of the cable manufactured as described above, where ■ is a conductor, 2 is an insulator, and 3 is a sheath.
各側のケーフルシースの偏肉率及び伸びを測定した結果

本発明の範囲にある実施例１〜６ではいずれも缶架橋時
の偏肉率は２０％以下であった。比較例１では充填剤の
配合量が少なすぎるため偏肉率が大きく、比較例２ては
充填剤の配合量が多すぎるため伸びが著しく低下する。In all of Examples 1 to 6 within the scope of the present invention, the thickness unevenness during can crosslinking was 20% or less. In Comparative Example 1, the amount of filler blended is too small, resulting in a large thickness unevenness, and in Comparative Example 2, the amount of filler blended is too large, resulting in a significant decrease in elongation.
比較例３．４では充填剤の平均粒径が本発明の規定値を
外れるため、偏肉率が大きくなっている。In Comparative Examples 3 and 4, the average particle diameter of the filler deviates from the specified value of the present invention, so the thickness unevenness ratio is large.

It is coated with a composition containing at least one type of filler selected from magnesium silicate, calcium carbonate, and hydrated silicic acid with a particle size of less than μ, and can prevent uneven thickness during can crosslinking, and also has excellent elongation properties. It becomes possible to realize a cable coated with a fluorine-containing elastomer.
