lightning/surge arrester

Due to the ZnO valve has excellent non-linear sound steep wave impact, the over-voltage arrester can be limited to a relatively low level, so as to provide reliable protection to the equipment. Compared with porcelain MOA, the composite jacket zero-lash ZnO arrester (hereinafter referred to as HMOA) has more stain resistant, ageing resistant, anti-explosive, anti-ultraviolet capability and smaller size, lighter weight. May reduces the equipment setup area, improves the exterior contamination and the environment condition to its influence.
