Drop out Type Polymer Composite Lightning Surge Arrester

Patent introduction Detachable drop-out arrester  Dropping arrester with detachment device combines the advanced concept of metal oxide arrester with the principle of drop-out fuse. Besides the overvoltage protection function of metal oxide arrester, the power frequency short circuit current can cause the disconnector action when the abnormal faculty occurs, the grounding terminal automatically disconnects, and the lightning arrester turns off and withdraws from the power grid operation. Meanwhile, the installation is convenient and the maintenance is simple, and the power supply reliability of distribution network is improved efficiently.   Model type Rated  voltage  of  arrester (kV) Nominal  discharge current (…
