What kind of material are the current arresters?
At present, the main is Zinc Oxide arrester, the new lightning arrester also has ceramic chip lightning arrester, etc., but at present is not too mature, more mature and commonly used is Zinc Oxide arrester
There are many kinds of Surge Arresters (arresters), which have exceeded over 100 kinds in the Chinese market. How to classify different types of arresters and brands may be placed before us. From the composite structure; now the arrester on the market there are several kinds: 1) clearance - open space, closed the gap between the 2) discharge tube types, open the discharge tube sealed discharge tube 3) varistor - monolithic and multi chip 4) diode 5) pressure sensitive resistance / gas discharge tube combination, simple combination, complex combination of silicon carbide) 6 types in accordance with its protective properties can be divided into: open circuit short circuit type lightning arrester, lightning arrester or switch type, voltage limiting type according to the working condition (installation) and can be divided into: parallel arrester and cascade type arrester.
