保定电气厂家价格-交流无间隙金属氧化物避雷器

无间隙线路避雷器主要用于限制雷电过电压及操作过电压；带外串联间隙线路避雷器由复合外套金属氧化物避雷器本体和串联间隙两部分构成，主要用于限制雷电过电压及（或）部分操作过电压。近十几年来，国内外采用带外串联间隙金属氧化物避雷器，大大提高了金属氧化物避雷器承受电网电压的能力，又具有更好的保护水平，因此EGLA（带外串间隙线路避雷器）是应用最广泛的线路避雷器

Gapless line arrester is mainly used to limit the lightning overvoltage and switching overvoltage; band gap series line arrester is composed of two parts of composite metal oxide surge arrester with series gap and body composition, is mainly used to limit the lightning overvoltage and switching overvoltage (or part of). In recent years, with the outer metal oxide surge arrester with series gap at home and abroad, greatly improving the ability of metal oxide arrester under voltage protection level, and has better, so EGLA (with gapped line arrester) is the most widely used line arrester
