Features of arrester with series gap □ Product model description1. Under normal conditions, the series gap of the arrester isolates the arrester from the system, and the arrester does not participate in the operation, thus prolonging its service life;2. For the system with frequent voltage fluctuation, the gap can be broken down to make the arrester work only when the voltage exceeds the specified value, avoiding the frequent action of the gapless arrester;3.

The main component of the metal oxide arrester's nonlinear resistance valve is zinc oxide, which has excellent nonlinear characteristics. Under normal operating voltage, the resistance value is very high, which is actually equivalent to an insulator. Under over-voltage, the resistance of the resistor is very small, and the residual voltage is very low. However, under normal operating voltage, the valve plate will deteriorate due to long-term power frequency voltage, which will cause changes in resistance characteristics and increase the leakage current flowing through the valve plate.
