The fin ite element models of an arrester, are established w ith the general fin ite element analysis sofwt are ANSYS, onemodel isw ith isolation, but another isw ithout. The in- ternal forces and displacements of the two models are calcu lated under w ind load ing, junction board load ing and horizontal seism ic loading respeclively. In comparison w ith the model w ith out isolation, the seism ic responses of themodelw ith isolation are reduced distinctly due to the effects of the isolation. The whole structure of the arrester w ith isolation is enough safe.
