Zinc oxide arrester It is a relatively new type of lightning arrester in modern times. Because of its small size and easy installation, it has been widely used. Compared with traditional porcelain arresters, zinc oxide arresters have the following advantages: 1. Zinc oxide lightning arrester has a very large resistance under normal voltage and exhibits excellent insulation performance. However, under the action of the voltage brought by lightning, it will show an abnormally low resistance, which will discharge the current brought by lightning, so that the equipment connected to the zinc oxide arrester will not be affected by the high voltage caused by lightning. 2. Simple structure, small size, easy to install. And there is no gap in the zinc oxide lightning arrester, which can effectively ensure that the residual voltage is lower than the safe value when the lightning voltage is discharged. 3. There is no time delay for the pressure release of the zinc oxide arrester. Once the voltage is turned on, the valve can immediately absorb the voltage energy, the response speed is very fast, and the protection effect is very good.
