ABSTRACT:
The suspension insulator of the present invention has an improved shape of the embedding portion of a metal pin, which is an embedding multi-step portion constructed with an inverted spherical convex trapezoid upper expanded portion having a larger surface at the top end and an inverted frust-conical lower expanded portion succeeding to the upper expanded portion. By using such a metal pin, the stress distribution of the insulating body is made uniform and therefore a small size and light weight of suspension insulator having high tensile strength is obtained.
