1.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.

2.Functional characteristics
Functional characteristics
1.The KBSG9-50-1600/10(6) mining flameproof of dry type transformer conforms to GB82862005 the requirement of “mining flame proof movable substations”, its no load, load loss is 10% 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,50Hz,ANAN 4.High strength, low temperature rise, good cooling and waterproof propert, and easy maintenance.

Service conditions
1.The installation is not higher than 1000m(normal)special environment gives explanation in addition
2.Ambient temperature
Highest temperature: 40C
Maximum monthly average temperature: 30C
Maximum annual temperature: 20C
Lowest temperature: -5C
3.The surrounding air relative humidity is not greater than 95%(25C)
4.In the mine,with methane, dust explosion danger is well
5.No vibration the gradient is less than 15C
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
