Mine transformer is a set of mobile supply, transformer devices. Used to change the size of the AC voltage, it is applicable to methane and coal dust mixed gas and other hazards in the mine. The 6KV, 10KV power supply into 400 (380), 693 (660), 1200 (1140), 3450 (3300) V coal mines required low-voltage power supply. Mine transformer shell for the whole ripple, both sides of the open-and open the lid structure, with high mechanical strength, low temperature, heat dissipation and good. Core selection of high quality low loss silicon steel, low no-load loss, no-load current, low noise. Using H-class insulation materials and advanced insulation structure, thermal stability, and can continue at full load under high temperature operation.
