The classification of zinc oxide arresters can be distinguished according to many aspects. Here, the classification of zinc oxide arresters is mainly introduced in detail based on the rated voltage value.

Zinc oxide arresters can be classified into high voltage, medium voltage, and low voltage ratings. These three categories are further subdivided into four levels.

According to the classification of the rated voltage, the zinc oxide arrester can be divided into three types:
1. High voltage
Refers to the series of zinc oxide arresters above 66KV, which can be roughly divided into four grades: 500kV, 220KV, 110KV and 66KV.

2. Medium voltage
Refers to the zinc oxide arrester series products in the range of 3KV ~ 66KV (excluding 66KV series products), which can be roughly divided into four voltage levels: 3KV, 6KV, 10KV and 35KV.

3. Low voltage
Refers to the zinc oxide arrester series products below 3KV (excluding 3KV series products), which can be roughly divided into four voltage levels: 1KV, 0.5kV, 0.38KV and 0.22KV.
