Main technical characteristics: 1) It highly utilizes the magnet-inductivity of cold-rolled silicon steel sheet and lowers the no-load current and no-load loss tremendously through annealing. Compared with model 9 product, its no-load current and no-load loss are 70% and 30% lower respectively than that of model 9. 2) Core is wound tightly with cold-rolled quality silicone steel sheets, which shows more advantages in tightness than that of laminated core, secures the entirety and decreases 5-7dB of noise after the annealing and painting processes 3) Coil windings are made up of the quality oxygen-free copper wires that are wound directly around the core, which simplifies the production process. 4) The corrugated structure of the oil tank leads to elegant outer appearance, compact volume, and small dimension.
