Enhanced Composite Wrapped Surge Arrester And Methods Of Providing The Same

Abstract: A solid dielectric surge arrester includes a hermetically sealed composite encased module assembly. The module assembly includes at least one metal oxide varistor (MOV) block with an outer circumferential surface, and a material applied to the outer circumferential surface. The material includes multiple layers to allow the module assembly to withstand a bending moment under long term cyclic load and short term rated bending load, the material is configured to improved bending strengths, and provide safe short circuit failure mode venting in a preferential direction or directions.
