10Mining Flameproof Dry Type Transformer

Product Description:
KBSG9 series mining flameproof dry-type transformersuit for not only mines filled with firedamp mixed gas, grime and explosive gas, but also the gas and steam environment that can not erode metal or destroy insulation. The transformer has the merit of high strength, low temperature rise, good cooling and waterproof property, and easy maintenance.

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: *0ºC Maximum monthly average temperature: *0ºC Maximum annual temperature: *0ºC Lowest temperature: *5ºC 
3. The surrounding air relative humidity is not greater than *5%(*5ºC) 
4. In the mine, with methane, dust explosion danger is well 
5. No vibration the gradient is less than *5ºC 
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
Mine filled with fire damp mixed gas, grime and explosive gas; The gas and steam environment that can not erode metal or destroy insulation.
