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.
