A galvanized metal cap is cemented to the outside of the line post head supporting the trunnion type clamp. Height compared to pin insulators.
glass insulators russia between conductor and earth, surrounding the insulator physique, along which electrical discharge may possibly take location by means of the air, is recognized as flashover distance.

Suspension insulators are tested in accordance with ANSI C29 & IEC1109 specifications. PPC tends to make ANSI approved Ball-Socket and Clevis type distribution suspension insulators for overhead distribution systems in the globe. A new design and style of insulator unit is describ- ed in which the possible distribution is stabilized by resistors.
As apparent from the above explanation, the present invention can stop disastrous accidents such as the separation of the cap and pin of an insulator unit resulting in a line drop of a power-transmission line and the like by intercepting extension of cracks with the compressive strain zone even when the shed portion was shot by a bullet such as a rifle and the like.
