本発明は、長期安定性にすぐれる電気絶縁ケーブルに関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electrically insulated cable with excellent long-term stability.
電気集塵機、イオン発生器等に用いられるケーブルとし
てＯＦケーブル、架橋ポリエチレンケーブル、ポリエチ
レンケーブル等が使われている。OF cables, cross-linked polyethylene cables, polyethylene cables, etc. are used as cables for electrostatic precipitators, ion generators, etc.

扱いも簡単であるが、実用時比較的短時間で絶縁破壊を
おこす。このため、取扱いが容易でかつ、長期安定性に
すぐれた電気絶縁ケーブルがのぞまれていた。Although OF cables exhibit stable characteristics, they have problems such as oil leakage and poor handling. On the other hand, cross-linked polyethylene cables and polyethylene cables are easy to maintain and handle, but dielectric breakdown occurs in a relatively short period of time during practical use. Therefore, there has been a need for an electrically insulated cable that is easy to handle and has excellent long-term stability.

。The present invention provides an electrically insulated cable characterized in that an insulator made of an ethylene-vinyl acetate copolymer and an ethylene-α olefin copolymer having a density of 0.91 or more is used as an insulator. In an electrically insulated cable using the above insulator, preferably an insulator containing 5 to 80% (by weight) of ethylene vinyl acetate copolymer, more preferably 5 to 3,596% (by weight) of vinyl acetate copolymer. .

層を０．８間押出した。Experimental Example After extruding 0.81 L#L of an inner semiconductive layer onto a 1M single wire conductor, 1M of an insulating material was extruded, and an outer semiconducting layer was extruded thereon for 0.8 L#L.
又架橋の必要なものは窒素雰囲気中（５Ｋｙ／ｃａ１１
）２００℃で２分間加熱架橋せしめた。Also, items that require crosslinking are prepared in a nitrogen atmosphere (5Ky/ca11
) Crosslinking was carried out by heating at 200°C for 2 minutes.

縁体材料、破壊時間を表−１に示す。A damped oscillating voltage with a maximum wave height voltage of 50 KV, a oscillating frequency of 5 MH21, and a time constant of 10 μsec was applied to the completed cable, and the number of times until breakage was determined, and the ratio to Comparative Example 1 was determined. Table 1 shows the insulator materials and breakdown times.
