Zinc oxide arrester
  • Metal zinc oxide shield is a high-tech product in the 1990s. It adopts zinc oxide resistor with excellent nonlinear volt-ampere characteristics, so the protection characteristics of the arrester under steep slope, lightning wave and operating wave are greatly improved than that of the traditional silicon carbide arrester. In particular, zinc oxide resistor has good steep slope response characteristics, no delay to steep slope voltage, operating residual low, no discharge electrical dispersion and other advantages. Thus, the inherent defects of silicon carbide arrester caused by steep slope discharge delay caused by high slope discharge voltage and large dispersion of operating wave discharge lead to high operating wave discharge voltage are overcome, making the protection margin under steep slope and operating wave greatly improved, and in terms of insulation coordination, the protection margin of steep slope, lightning wave and operating wave can be made close to the same. Thus, the b
