11kv three phase distribution transformer 500kva performance advantages:

1.high efficiency and energy saving

Adopting high-permeability silicon steel sheets and pure copper windings , the no-load loss and load loss are significantly reduced. The S13 energy efficiency grade is higher, with lower long-term operation energy consumption costs, meeting the energy-saving access requirements of various countries.

2.durable and reliable

With anti-corrosion spray coating and high-quality cold-rolled steel plate,the sealing structure of fuel tank is tight, preventing oil leakage and ensuring long-term operation outdoors all day long without failure. Because it is wound with high-quality copper coils,11kv three phase distribution transformer 500kva has excellent conductivity, resistance to oxidation and aging. It will not age over a long period of time, making it safer and more reliable for you to use.

3.stable operation

The excitation current is small, achieving high energy efficiency and reducing the burden on the power grid. It has low noise, suitable for various sensitive scenarios. The temperature rise is controlled reasonably, extending the equipment's lifespan. It has strong resistance to short circuit impacts, capable of handling sudden failures and it can adapt to frequent changes in load and meet complex electricity usage requirements.

11kv three phase distribution transformer 500kva ensures the safe and stable power supply for the downstream equipment with a small excitation current, low noise, reasonable temperature rise control, strong anti-short-circuit impact capability, and the ability to adapt to frequent load changes.

4.convenient installation

with an integrated overall structure,It adopts the ONAN oil-immersed self-cooling cooling method, without the need for additional cooling equipment. The structure is compact and occupies a small area. It supports various installation methods such as outdoor poles, racks, and ground-based installations.
