Abstract
A lightning arrester module is double-enclosed to insure adequate environmental protection to the enclosed varistors as well as to contain the internal components of the arrester upon severe fault conditions. The internal components including the varistors are compressed within one half section of the inner enclosure and can be handled and tested without disengagement. The other half section of the inner enclosure is positioned over the internal components to complete the inner enclosure before the outer enclosure is arranged thereover to complete the lightning arrester module assembly.
