SEISMIC ISOLATION BEARINGS OF ELECTRIC INSULATOR

摘要

PURPOSE: An earthquake exclusion apparatus of an insulator for electric installation is provided to effectively absorb impacts added to an insulator body part in the earthquake state by installing a vibration isolation device. CONSTITUTION: An earthquake exclusion apparatus(100) of an insulator for electric installation comprises an insulator body part(110). The earthquake exclusion apparatus comprises a vibration isolation device(120) which is coupled and fixed to the insulator body part. The vibration isolation device comprises a first cover(121) and an absorbent member(122). Materials having elasticity comprise at least one among rubber, silicon, and synthetic resins. A supporting part(130) can be fixed and coupled to external facilities. An elastic member(140) is arranged to the outer side of the vibration isolation device. A coupling part(160) comprises a bolt and a nut for coupling the elastic member and the insulator body part.
