21kV Electrical Surge Arresters: Unyielding Metal Oxide Zinc Protection with Gapless Innovation
Introducing our state-of-the-art Polymer Lightning Arrester, more widely recognized as a surge arrester. This marvel of engineering harnesses the exceptional nonlinear volt-ampere characteristics of zinc oxide. In everyday operational conditions, the current that traverses this arrester is incredibly minimal, at mere microampere or milliampere levels. However, when faced with overvoltage, the arrester's resistance plummets dramatically, efficiently dissipating the overvoltage energy and providing robust protection. Our groundbreaking design distinguishes itself from traditional devices by eliminating the discharge gap, instead relying on zinc oxide's nonlinear properties to ensure effective leakage and interruption. Without such a safeguard, a lightning strike could unleash thousands of volts upon an electrical system, wreaking havoc by damaging transmission lines and potentially inflicting severe harm on transformers and other critical electrical equipment..
