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.

Competitive Advantage:
?
1. The transformer is mine use explosion proof type and has excellent explosion proof performance and mechanical strength.
2. Special design for inner construction, in case of inner construction was loosened in the term of delivery.
3.? The transformer has the strong capable of withstand thermal shock. It be able to overload and has the ability to withstand short circuit, low loss, a small amount of partial discharge and good insulation.
4. It is insensitivity to temperature and dust.
5. All insulation materials doesn’t combustion-supporting, self-extinguishing, non-toxic, excellent performance of fireproof, the transformer owned the characteristics like no harmful gases, low noise and no pollution.
6. it’s easy to use and maintain
7. Adopt C level of Nomex paper-covered wire from DuPont USA, it owned such features as air insulation, cooling, non-pollution, long lifetime and can be recycled.
8. Adopt the high quality 30Q130, 27Q120 cold rolling silicon steel and oxygen free copper conductor, the actual total loss is lower than similar foreign products, energy conservation and noise reduction.
