Coal Mine Explosion Proof Transformer Thermal , Silicon Steel
Description:
Resistance heating furnace transformer for mechanical parts, heat treatment, powder metallurgy sintering, and other non-ferrous metal smelting furnace of resistance and salt bath furnaces. Since the resistance of the heat generating element is too small, or the heating element in the heating process is too large change in resistance, it is necessary between the grid and the furnace with a resistance furnace transformer to reduce the input voltage and the electric adjustment.
Mine use explosion proof dry-type transformer suitable for underground mines containing methane mixture gas and having potential danger of coal dust explosion. The transformers were be worked as the distribution equipment for a large variety of electrical equipment, like pumping station, conveyor, mining machine and so on. The transformer suitable for used in coal mine, non ferrous metal mine and tunneling.
