Oil Immersed Mining General Power Transformer (KS9

1. Altitudes less than 1000m; 2. Maximum temperature 40 °C; 3. Minimum temperature of -20 °C; 4. The maximum daily average temperature 25 °C; 5. The highest annual average temperature is 20 °C; 6. Relative humidity of not more than 95% (when the air temperature is 25 °C); 7. Although installed in the mine dust, gas, but no possibility of explosion; 8. Supply voltage sine wave. The series of high quality low loss transformer core made of grain oriented silicon steel sheet, low no-load loss, load current, low noise. This series transformer adopt silicon steel sheet iron core which is made of excellent low loss crystal granule. They have the merit of low no-load loss, small no-load current and low noise.Functional characteristics 1. Adopt silicon steel sheet iron core which is made of excellent low loss crystal granule. 2. Low no-load loss, small no-load current and low noise.Service conditions 1. The height of sea level is less than 1000m. 2. Highest temperature 40º C 3. Lowest temperature: -20º C 4. Maximum daily average temperature: 25º C 5. Maximum annual mean temperature: 20º C 6. The relative humidity is less than 95%(when the sir temperature is 25º C) 7. Install at the site with dust methane, but no explosion water 8. Power supply voltage profile approximate to sine waveScope of application It suit for cetre substation, mine stop, general wind dypass and main wind dypass which has gas but no explosion danger, and the moisture Environment
