35kV MOA Metal Oxide Arrester adopts a structure with a gap. During normal operation, the insulation gap bears the operating voltage, and the ZnO resistor does not bear the voltage, so there is no aging problem. Installed and used in parallel with the insulator, the current flow performance is increased to 120kA, and the lightning protection level of the line is significantly improved. (Taking C1 and above multiple minefields as an example, the lightning trip rate was 8-12 times/(100km a) before the lightning protection transformation of the 35kV line. /100km a.)
