The invention discloses a zinc oxide surge arrester. The component contents by weight percentage are as follows: bismuth oxide: 3.5%-4.0wt%, nanometer antimony oxide: 2.7%-3.6wt%, cobalt oxide: 1.0%-1.8wt%, silicon oxide : 0.6%-1.3wt%, manganese oxide: 0.6%-0.9wt%, chromium oxide: 0.8%-1.4wt%, nickel oxide: 0.06%-0.14wt%, yttrium oxide: 0.8%-1.2wt%, ytterbium oxide : 0.8%-1.2wt%; the balance is zinc oxide; it solves the problem that the low potential gradient of the zinc oxide arrester causes the equipment to be bulky, and the outlet room for user wiring is small, so the equipment occupies a large area, production and transportation, The installation cost is very high, coupled with the large consumption of raw materials, which poses a huge threat to raw material resources and other technical problems. |
