Embodiment Construction
[0012] A zinc oxide resistor with high side flashover voltage, comprising a zinc oxide resistor body, the outer surface of the zinc oxide resistor body is sequentially coated with a high resistance layer and a surface glaze layer, and the zinc oxide resistor The outer surface is wavy, and the extension direction of the wavy zinc oxide resistance sheet wave is consistent with the thickness direction of the zinc oxide resistance sheet.
[0013] For the above-mentioned zinc oxide resistor, preferably, the high-resistance layer and the surface glaze layer are closely integrated with the main body of the zinc oxide resistor through high-temperature sintering.
[0014] For the above-mentioned zinc oxide resistor, preferably, the junctions between the two end surfaces and the outer surfaces of the zinc oxide resistor are arc angles.
[0015] For the above-mentioned zinc oxide resistor, preferably, the body of the zinc oxide resistor is a rotating body with a wavy outer surface.
