 Functional characteristics
1. The KBSG********0/*0(6) mining flameproof of dry type transformer conforms to GB********5 the requirement of "mining flame proof movable substations", its no load, load loss is *0% less than original standard the no-load current short-circuit impedance has diminished too.
2. The insulation material adopt the H level or the C level insulation material, the thermal is good, it is suit for long time operation
3. 3 Phases, *0 Hz, ANAN
4. High strength, low temperature rise, good cooling and waterproof propert, and easy maintenance.

Service conditions
1. The installation is not higher than ***0m(normal)special environment gives explanation in addition
2. Ambient temperature
Highest temperature: *0C
Maximum monthly average temperature: *0C
Maximum annual temperature: *0C
Lowest temperature: *5C

3. The surrounding air relative humidity is not greater than *5%(*5C)
4. In the mine, with methane, dust explosion danger is well
5. No vibration the gradient is less than *5C
6. No gas or steam to corrode metal needed or destroy insulation
7. Non-water drop sit
8. Power supply voltage profile approximate to a sine wave
9. The three-phase supply voltage approximate symmetrical

Scope of application ( powertransformer.cn )
Mine filled with fire damp mixed gas, grime and explosive gas; The gas and steam environment that can not erode metal or destroy insulation.
