Abstract
A surge arrester including an outer elongated housing and an inner liner is disclosed herein. The outer housing is constructed of a material which will not break as a result of internal electrical arcing, specifically a relatively resilient, electrically insulating and non-tracking material which in a preferred embodiment is EPDM rubber. In order to add structural integrity to the arrester, its inner liner is constructed of a high strength material, preferably resin impregnated fiberglass.
