は、ケーブルを受けるように作られている。This insulator consists of a central rod 1 made of fiberglass which is glued together with resin at one end 2 which is fixed to a housing 4 in a part 5 with a metallic fitting forming the base. This other end 3 is provided with at least one notch and is glued to a fixing head 7 made of thermosetting resin, for example by overmolding. (The notches can be replaced by other treatments.) The head 7 has a side channel 8 and a top channel 9. The external surfaces of the fixing head 7, the rod 1 and the mounting part 5 have an elastomer coating 10 overlaid thereon. In the head 7 this coating forms a top groove 19 above the channel 9 and a side groove 18 above the channel 8. These two standardized sized grooves are made to receive the cable.
表示されている被覆１０は、種々の輪郭及び種々の直径
をしているひだ１１を含む。The illustrated coating 10 includes corrugations 11 of different contours and different diameters.

では、この値は碍子のヘッドが破壊する歪みに非常に近
接しているのに対し、本発明の碍子では、破壊は歪みが
約５０ｍｇ＋、対応する荷重で４３００１ｂｓの時のみ
にしか破壊しない。Regarding the bending strength, the insulator of FIG. 1 was embedded in a testing machine to observe the load and corresponding strain. The NSI standard values require a bending strength of 2800 lbs. For this value, the observed strain is 28 am, compared to several II for the porcelain insulator. For porcelain insulators, this value is very close to the strain at which the insulator head breaks, whereas for the insulator of the present invention, failure occurs only at a strain of about 50 mg + and a corresponding load of 43001 bs. .
規格化された接着によって固定された溝１８の溝１９中
に受けられるケーブルは、長く作動してもケーブルを傷

碍子が小球の衝撃を受けても、磁器碍子の場合のような
衝撃による全体構造の破壊または粉砕は起こらない。Even if the insulator is impacted by a pellet, the overall structure will not be destroyed or shattered by the impact, as is the case with porcelain insulators.
