Product Description

Introducing the 21kV Electrical Surge Arresters - a premier solution for safeguarding your electrical systems. This advanced Metal Oxide Zinc Arrester is specifically designed as a Gapless Type to provide exceptional safety and reliability.
Discover the cutting-edge Polymer Lightning Arrester, also known as a surge arrester. It harnesses the superior nonlinear volt-ampere characteristics of zinc oxide, ensuring that the current through the arrester remains minimal (at the microampere or milliampere level) under normal voltage conditions. When an overvoltage occurs, this innovative design allows the resistance to decrease sharply, effectively releasing the energy of the overvoltage and providing robust protection. Unlike traditional arresters, this model features a gapless design that leverages the nonlinear characteristics of zinc oxide to manage leakage and disconnection seamlessly. In the unfortunate event that protection is absent or fails, the electrical system could suffer from a lightning strike, potentially generating thousands of volts and inflicting substantial damage on transmission lines, transformers, and other vital electrical equipment. Choose our arrester for peace of mind and unwavering protection..
