The main component of the nonlinear resistor valve piece of the metal oxide arrester is zinc oxide. The zinc oxide resistor piece has extremely superior nonlinear characteristics. Under normal operating voltage, its resistance value is very high, which is actually equivalent to an insulator. However, under the action of overvoltage, the resistance of the resistor sheet is very small and the residual voltage is very low.
Arrester manufacturer
The core working components are fired from multi-element metal oxide powder mainly composed of zinc oxide, which has excellent nonlinear volt-ampere characteristics, fast steep wave response and large flow capacity. Products with gaps use self-blowing gaps and a pressure-equalizing irradiation structure, which reduces the dispersion of discharge and has a small impact coefficient. The use of composite insulation jackets conforms to the international development trend of miniaturization, safety and maintenance-free power products. Compared with traditional inorganic materials such as ceramics and glass, polymer organic composite materials have the advantages of small size, light weight, resistance to dirt and cleaning, explosion-proof and vibration-proof. It is a must-select lightning protection component in integrated and modular medium and high-voltage power transmission and transformation equipment
