Description
Product Introduction: The rear-plug surge arrester connects with a front plug or another rear plug to provide overvoltage protection for electrical equipment. The arrester models used in transformer neutral-point ungrounded systems (18/20kV) are: YH5WZ-32/85 (station type), YH5WX-34/90 (line type). The arrester models used in transformer neutral-point grounded systems (12/20kV) are: YH5WZ-26/66 (station type), YH5WZ-32/85 (line type). Product Features: The valve discs inside the plug-in arrester have good nonlinear characteristics, giving the arrester low residual voltage, large discharge capacity, fast response time, and flat steep-wave characteristics. It effectively prevents lightning strikes, switching surges, and overvoltage, ensuring the operation of power transmission and transformation equipment.
