Product Description

Presenting the exceptional 21kV Electrical Surge Arresters! These Metal Oxide Zinc Arresters boast a cutting-edge Gapless Type design.
Our sophisticated Polymer Lightning Arrester, alternatively known as a Surge Arrester, harnesses the remarkable nonlinear volt-ampere characteristics of zinc oxide. At a normal operating voltage, the current flowing through this state-of-the-art arrester is minimal, measured in microamperes or milliamperes. However, when overvoltage occurs, the resistance decreases dramatically, swiftly releasing the overvoltage energy and providing unparalleled protection. This highly advanced arrester distinguishes itself from traditional models by eliminating the discharge gap, utilizing the superior nonlinear properties of zinc oxide for effective leakage control and interruption. In instances where protection is absent or fails, electrical systems risk exposure to lightning strikes, generating thousands of volts that can severely damage transmission lines and inflict catastrophic harm on transformers and other vital electrical equipment..
