3. High efficiency, no need for frequent expansion of production capacity, reduced investment and operating costs.
4. Wide adaptability, suitable for scenarios with large elevation changes, intense agricultural seasons, industrial loads, etc.
5. Eco-friendly and environmentally friendly, with low loss and low noise, meeting the requirements of energy saving and environmental protection.
1. Basic performance parameters (customizable)
Rated power: 50 kVA - 63000 kVA
Voltage regulation method: Supports on-load tap changers (OLTC) and no-load tap changers, the voltage adjustment range of the tap changer can be customized.
Cooling method: ONAN / ONAF
Oil Cooling: Default is Natural Cooling (ONAN), upgradeable to Forced Air Cooling (ONAF) or Forced Air Cooling with Oil Circulation (OFAF).
Connection group: Dyn11, Yyn0 (main stream)
Energy efficiency class: Highly efficient energy saving system.
Winding: oxygen-free copper conductors are used, multi-layer segmented and step winding technology is applied, the winding surface is made of several layers of high-quality insulating materials, there are insulating gaskets that provide complete insulation protection.
Oil tank: Sealed corrugated oil tank, excellent sealing performance, prevent oil leakage, good corrosion resistance. Product advantages:
High overload capacity, ability to withstand short-term peak loads and ensure uninterrupted power supply.
There is no need to adjust the system to meet peak loads, which reduces initial investment and expansion costs, ensuring high cost efficiency.
Available in oil ordry cooling, suitable for various application scenarios, with a flexible voltage range.
2. Typical application scenarios:
- Rural power grid: solving the problem of short-term load increase during the Spring Festival and agricultural season, reducing the cost of power grid modernization.
- Industrial sector: withstanding shock loads when starting electric furnaces and electric motors, resistance to harmonics and ensuring uninterrupted production operation.
Urban distribution network: balances peak and off-peak loads, improves equipment utilization, and is suitable for residential and commercial areas.
- New energy sources/infrastructure: adaptation to fluctuations in the connection of photovoltaic and wind power plants to the grid, ensuring a stable power supply for data centers and rail transport.
