>Power transformer is main primary equipment in power grid, especially on long distance transf-ormation.
>General type is used for up and down voltage ,auto transformer is used for coupling power system with different voltage level.
>There are various types power transformer such as double winding, triple winding, off circuit tap change, on load tap change, high impedance.
>Apply to grid power station, hydropower station, thermal power plant, industrial power station and soon.
>GNEE using high purity copper winding, Bao-steel high performance CRGO four stages lamination, loss level could better than GB and IEC standard.
>Using processes like tension plate, cushion block precompression, outside and inside gagger to guarantee performance of loss level, dynamic stability, heat stability, and noise level.
>Nice appearance with bending corrugated bell jar type oil box.
> The shell
- ABB robot automatic welding, laser detection, to avoid leakage, pass rate of 99.99998%
- Electrostatic plastic spray treatment, 50 years do not take off the paint (coating corrosion resistance within 100h, hardness ≥0.4)
- Sealed structure, maintenance-free, normal operation life of more than 30 years
> The iron core
- The iron core is made of high quality cold-rolled grain oriented silicon steel sheet with mineral oxide insulation (from Baosteel and WISCO of China).
- By controlling the cutting and stacking process of silicon steel sheet, the loss level, no-load current and noise can be minimized
- The iron core is specially reinforced to ensure the structure of the transformer is firm during normal operation and transportation
> Winding
- The low voltage winding is made of high quality copper foil with excellent insulation resistance
- The high-voltage winding is usually wound with insulated copper wire, using the technology patented by hengfengyou electric
- It has very good ability to bear radial stress caused by short circuit
