        Purpose
        The product is applied for underground environment containing methane mixture gas and coal dust with potential explosion hazard. It can be grouped into a mining flame proof mobile substation with the HV switch and LV switch. Or it can be used separately as a flame-proof transformer together with the explosion-proof outlet box.

                                                                                                                                               
        Characteristics
        1, With excellent explosioin-proof performance and adequate mechanical strength.
        2, Designed with no-lifting core structure to prevent the product internal loose during transportation.                                                     
        3, Adapted to a variety of mine conditions through lifting vertically.
        4, By using cylinder- type coil to make impulse voltage distribution uniform,so that achieving HV winding strong resistance to over voltage impact.
        5.Adopted vacuum pressure impregnation process, HV and LV coils wound with same mold, having the effect of high strength and anti short circuit ability.
        6. Made of much Class C insulation materials, high thermal shock resistance, high over load capacity, and good insulation performance.
        7.No sensitive to temperature and dust. Nonflammable, Fire-retardant, no harmful gas, low noise, no pollution. Maintenance free under normal  use.
