PRODUCT FEATURE
The world's most sophisticated over-voltage protection is the zinc oxide surge arrester. Because zinc oxide arrester is mostly used to manufacture the resistor disc of the core component. This product's prescription significantly enhances the resistor disc's volt-ampere characteristics and boosts its through-current capability at over-voltage in comparison to the traditional silicon carbide arrester, resulting in a radical local shift in the arresters' characteristics.
