Abstract:
    A suspension insulator includes a compressive strain of more than 60x10-6 in the ceramic insulator body at least in the circumferential direction in the vicinity of the shed root of the ceramic head portion of the suspension insulator, whereby a suspension insulator causes no accidents such as separation of cap and pin of suspension insulator, line drop of power transmission lines and the like, even when shot by a rifle.
