Overview
HY1.5W 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
1. Altitude: ≤ 2000 meters;
2. The environment temperature: upper limit +40℃, lower limit -40℃;
3. Maximum wind speed does not exceed 35m/s;
4. Earthquake intensity: ≤7degree;
5. AC systen frequency is 50Hz or 60Hz;
