GNEE Steel main power transformer
S11/S13 series oil immersed power transformers use insulating oil as cooling and insulating medium.The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor.Vacuum oil injection process is adopted to effectively prevent oxygen and water from penetrating into transformer oilresulting in the decline of insulating oil performance.It is a new generation of energy-saving and environmental protection products.

Oil Immersed Power Transformer Feature
> 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
