Overview
HY5WZ Surge Arrester are high-tech products in the 1990s. They use oxygen zinc resistors with excellent nonlinear volt-ampere characteristics, so the protection characteristics of the arrester under slope, lightning waves, and operating waves are greatly improved compared to traditional silicon carbide arresters.
Operating Conditions
