The Oil Immersed Transformer series are the kind of the transformer with low noise, low loss and low partial discharge. With rational structure, high-quality material, scientific design, strict craftsmanship and advanced test method, the characteristics of this series products are as follows:

- Excellent dynamic thermal stability, outstanding short-circuit resistance, high lighting impulse resistance, high reliability.
- With excellent overload capacity, it can long-term operate under 110% load.
- Low lose, energy conservation, run economically and maintenance free.
- Contour artistic, compact size, low installation and maintenance costs.
- Performance and parameter conform to or excel the standards of IEC.
- Fully Hermetically oil tank, effectively preventing air from eroding oil and prolonging the service life of the transformer

Advantage:
-  Low loss, low noise, low partial discharge, high reliability
-  Powerful anti-short circuit capacity, high anti-lightning impulse capacity
-  HV coil is Vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure.
-  Simulating analys is being used in the core model, the resonance can be avoided and the noise is reduced.
-  Simulation calculation and analysis of lightning impulse wave are applied to HV Coils; anti-lightning impulse capability is improved.

Process Technology: 
Core:

- Our transformer's core is made of high quality cold rolled grain oriented silicon steel sheet with high magnetic permeability. It is using full 45° slope lamination, so that the noload loss and the no-load current are reduced efficiently. 

LV Winding:

HV Winding

- We use our existing technology calculate and analysis Lightning wave process simulation. Then substantially improving product's antilighting capability.
