6kV～10kV系统用复合外套金属氧化物避雷器性能满足 JB/T 8952-2005《交流系统用复合外套金属氧化物避雷器》及GB11032-2000《交流无间隙金属氧化物避雷器》两个标准的规定。配典型保护相应电压等级的开关柜、箱式变电站、电力电缆出线头、柱上油开关等配电设备免受大气和操作过电压的损坏；电站型保护发电厂、变电站的交流电气设备免受大气和操作过电压的损坏；线路型用于线路悬挂，进行沿线保护，从而降低了整个系统的过电压水平。
The performance of composite coated metal oxide arresters for 6kV-10kV systems meets the requirements of JB/T 8952-2005 "Composite coated metal oxide arresters for AC systems" and GB11032-2000 "AC gap-free metal oxide arresters". Distribution equipment such as switchgear, box substation, power cable outlet, oil switch on column with typical protection of corresponding voltage level is protected from damage of atmospheric and operating overvoltage; AC electrical equipment of power plant and substation is protected from damage of atmospheric and operating overvoltage; Line type is used for suspension of line to carry out operation. The protection along the line reduces the overvoltage level of the whole system.
