3、，证明阀片荷电率可提高到 87%，能满足原电力部安检司及新国标 GB 11032-2000 关于提高部分避雷器额定电压和持续运行电压的要求。1998 年通过 ISO9001 国际质量体系认证，并获得电力部成套局、水电水利规划局颁发的“入网证” ，产品列入国家经贸委颁发的“全国城乡电网改造推荐设备名录” 。本公司产品全部满足或优于 GB 11032-2000、IEC 60099-4 及其他相关部标。Metal oxide surge arrester without gaps is the most advanced over-voltage protector in the world. It
4、 is used in protecting electrical equipment to avoid damage from atmospheric over-voltage it is indispensable equipment in safe run of power system.Our company has manufactured zinc oxide varistor (ZnO) since 1984. The quality of our products is one-up in china, its residual voltage ratio is little
5、and ageing performance is good. Our arresters, which are made of the varistor, have been approved by former energy sources ministry and machinery the charge ratio of it was proved that may raise 87%. So our products can satisfy the requirement of former electric power safety examine ministry of Chin
