Drop Arrester
Drop type (drop type, detachable type) lightning arrester is a distribution type zinc oxide lightning arrester that is modified and skillfully installed on the drop type mechanism of the drop type fuse, so that the lightning arrester can be easily detected, repaired and replaced with the help of an insulating switch lever under the condition of continuous power supply, which not only ensures the smoothness of the line, but also greatly reduces the work intensity and time of power maintenance personnel, It is especially suitable for places where power failure is not appropriate, such as post and telecommunications, airport stations, hospitals, prosperous business districts, etc

The second generation of drop arresters has added disconnectors. When an accident occurs to the arresters, the disconnectors are activated by using power frequency short circuit current to automatically disconnect the grounding terminal of the disconnectors, and the arrester elements are overturned and removed from operation to prevent further expansion of the accident. It is also easy for maintenance personnel to find out and replace the disconnectors in a timely manner. Its falling principle is similar to the falling of fuse pipe caused by fuse fusing. Our company has adopted the most advanced international thermal explosive release device, which has the advantages of fast action speed, wide action current range, and can withstand the specified current impact and action load.
