Dear Sir，

It is very nice for us to introduce our updated protector for Oil-immersed transformer,this equipment can completely prevent explosions and fires for big oil-immersed transformers ranging from

5MVA-1000MVA to avoid potential and existing risks of transformers happening, it is the unigue safety device we are making in the world.

As you might know that each year there are so many self-explosion and fire of oil-immersed transformer worldwide caused: over-use,over-temperature,ageing of insulation and so on,Unfortunately，the existing Self protection device cannot prevent transformers from explosion and fire and our safety equipment can completely prevent transformers from explosion or fire within 10 ms (10  millisecond), it is unique and most effective device worldwide.

So, what we can ensure you is that: No more explosion and fire for oil immersed transformer and oil tanks within 30 years.any details you can see the new attachments.
