The Drop-out arrester is a kind of lightning arrester, which is skillfully installed on the drop type mechanism after refitting the distribution type zinc oxide arrester.When the power is not cut, the arrester can be tested, repaired and replaced with the help of load-break operating hook stick tool. It not only ensures the smooth running of the line, but also reduces the working intensity and time of the power maintainers. Especially suitable for unsuitable places such as communication, airport, station, hospital, etc.
1. The other performance of it is the same as the distribution arrester.
2. The drop arrester is with disconnector , when the lightning arrester appears abnormal fault, the power frequency short-circuit current is used to make the detach move, so that the grounding end of the detach can be removed automatically, the arrester will be turned over, and the accident will be prevented from expanding further by withdrawing from operation. And easy to maintain the timely discovery of maintenance and replacement.
