   >>GB1094.3, 5-1985.

2. Low loss
- Optimization of electromagnetic calculations, using combined technology of electrical shielding and 
 magnetic circuit, effectively controlled leakage, so as to reduce the load loss and to avoid partial  
- Use high quality cold-rolled lattice orientation high permeability silicon steel, to reduce the load loss, 
 no-load current.
- Core all-helical stacking with STEP joints, and advanced stacking process, reduced the load loss, load   
 current and electromagnetic noise.

3. Low partial discharge
To ensure the safe and steady operation of the transformer under continuous rated voltage, our Electric Power Research Institute conducted a lot of research to develop a more reasonable insulation structure, plus the strict technology specifications and technical staff experience, ensured the low partial discharge of our products.

4. High strength
