The composite ZnO lightning arrester (surge arrester) is the crystallization of composite insulator and zinc oxide lightning arrester research achievements, which has overcome the shortcomings of porcelain arresters by advantages of composite insulation materials. The excellent characteristics are displayed on following several aspects: (1) good sealing performance due to the whole molding process to solve the damp problem, and the expected test cycle can be extended to five years. (2) compact structure with less spare parts; small weight, convenient for transportation; the installation can effectively utilize the existing cross arm of fuse cutout, saving the cross arm of the original lightning arrester;(3) good insulation performance and strong pollution-resistant ability. There is no need to clean it during operation; no altitude restriction; running time is more than 20 years; (4) excellent explosion-proof performance, elastic soft skirt ensures no splash when the lightning arrester gets failure, keeping people and equipment safe; (5) good protection performance, high action and load capability; it can endures repeated lightning shock, which improves the reliability of lightning power system; The composite ZnO lightning arrester has excellent performance, especially the corrosion-resistant and explosion-proof characteristics, which will become the upgraded product of low and medium voltage lightning arresters.
