ZnO resistor is the core element of the lightning arrester. It mainly protects power system equipment by limiting lightning overvoltage to ensure that the line does not trip.

The performance indicators of ZnO resistors mainly include potential gradient, flow capacity, and nonlinear coefficient, which are determined by the formula and process on the macro level and by the "ZnO grain-boundary layer" characteristics on the micro level.

YF POWER, as a professional manufacturer of MOV blocks, provides you with brilliant-performance zinc oxide disc. We have focused on developing Zinc Oxide blocks for surge arresters since established. Our high-quality, high-performance Zinc Oxide blocks are available in various sizes tailored for applications ranging from light to heavy-duty, suitable for both AC and DC environments, and adaptable to different installation conditions. If you require ZnO blocks, don't hesitate to contact us.
