USAGE: ENVIRONMENTAL CONDITION
1. Ambient temperature: no higher than+40 ºC, no lower than - 40 ºC;
2. Altitude: no more than 3000m;
3. Power frequency: 50 ± 2Hz; 60±2Hz;
4. Maximum wind speed: 35m/s;
5. Cleaning-free conditions: areas with medium pollution and below;
6. For gapless products, the power frequency voltage applied for a long time shall not exceed the continuous operation
voltage of the arrester;
