Jiangsu Unita Electric Equipment Co.,Ltd.（JSZONMA）can supply you with the high performance distribution transformers according to your requirements. If you need more information, please feel free to contact us.
This 50kVA 33kV/0.44kV oil-immersed transformer is an efficient power equipment suitable for outdoor power distribution networks. It adopts a three-phase double-winding design, which can safely and efficiently convert 33kV high-voltage electrical energy into 400V/440V low-voltage power supply. It is widely used in substations, industrial and mining enterprises, and urban and rural power distribution networks.
Core performance and parameters:
- High reliability: The main body uses high-quality mineral oil as the insulation and cooling medium, combined with a fully sealed corrugated oil tank structure, which effectively isolates moisture and oxygen, slows down oil deterioration, and features maintenance-free operation.
- High efficiency and energy saving: The iron core uses high-magnetic-permeability cold-rolled oriented silicon steel sheets, significantly optimizing no-load loss and load loss, resulting in remarkable energy-saving effects during long-term operation.
- Stable regulation: A ±5% (or ±2×2.5%) tap is provided on the high-voltage side, facilitating flexible adjustment of the output during voltage fluctuations. The standard Dyn11 connection group is equipped, which can effectively suppress harmonics and adapt to unbalanced loads.
- Heat dissipation and protection: The ONAN (oil-immersed self-cooling) cooling method is adopted, with natural circulation for heat dissipation. An oil reservoir, pressure relief valve, and gas relay are provided, offering multiple safety protections.
The product is strictly manufactured in accordance with international standards such as IEC60076, and possesses extremely strong weather resistance and anti-short-circuit capabilities. It is an ideal power distribution solution for ensuring the stable operation of the power system.
