Application of Mining Explosion Isolation Dry Transformer in Mining

General introduction of KBSG9 series mining flameproof dry-type transformer:

KBSG9 series mining flameproof dry-type transformer suit 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.

i. The three-phase supply voltage approximate symmetrical

The 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.

Product features(advantages )of KBSG9 series mining flameproof dry-type transformer:

A.The KBSG9-50-1600/10(6) mining flameproof of dry type transformer conforms to GB8286-2005 the requirement of "mining flameproof movable substations", its no-load, load loss is 10% less than original standard the no-load current short-circuit impedance has diminished too.

B.The insulation material adopt the H level or the C level insulation material, the thermal is good, it is suited for long time operation

C.3 Phases, 50 Hz, ANAN

D. High strength, low-temperature rise, good cooling and waterproof propert, and easy maintenance.
