2500KVA Dry Type Flameproof Transformer Mobile Transformer
2500KVA Mine use explosion proof 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.

JB4262-92Rubber cable introduced for explosion proof electrical
The altitude is less than 1000M
The maximum temperature40 ℃,The minimum temperature-5 ℃,
Relative humidity less than 95%( 25 ℃)
Underground mines containing methane mixture gas and having
potential danger of coal dust explosion
No strong bump and vibrate, the vertical surface less than 15
There is no the gas and steam that could corrosive meter or damage
the insulation in the environment
The waveform of power is similar to sinusoidal wave
Three-phase voltage approximate to symmetrical
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
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
