YH10W-48C1500 Station Type Surge Arrester 48KV 10kA without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared silicon carbide surge arresters.
2. Normal service conditions: 1. The ambient temperature: -40°C ~+40°C 2. The altitude above sea level : not exceed 1000-2000m 3. Earthquake intensity: not higher than 7 degrees; 4. Maximum wind velocity : less than 35m/s. 5. The filthy area should be given clear indication.
