Power Transformer Applications:

Apply to power plant (station), substation (power distribution station) and industrial etc.

Performance Features:

· Low loss: complies with the energy efficiency requirements in the "Power Transformer Energy Efficiency Limit Values and Energy Efficiency Levels" standard.

· Low noise: The self-cooling noise level will reach below 60dB.

· Low partial discharge: The amount of partial discharge is controlled below 100pc.

· Strong short-circuit resistance: the inside of the coil is supported by a high-quality insulating skeleton, and the side wall of the fuel tank is formed by laser cutting in one step.

· Beautiful appearance: All rust can be removed by ground grinding, and powder electrospray painting can achieve the effect of home appliance painting.

· No leakage: The sealing flanges adopt groove structure, the oil drain valve adopts copper valve, and the radiator adopts vacuum butterfly valve to ensure sealing performance.

Power Transformer Features:

1.Low partial discharge to ensure stable and reliable operation of transformer.

2.Low noise, reducing noise pollution to the environment.

3.Low temperature rise, strong overload capacity.

4.Low loss, energy structure optimization.

5.No leakage, high transformer sealing performance.

6.High impedance, high short-circuit resistance, providing the safety performance of the transformer.

Power Transformer Overview：

35kV oil-immersed power transformer power system substation and 35KV user station. The iron core is made of high magnetic permeability oriented cold-rolled silicon steel sheet. The coil is made of pie structure. The body is made of formed insulating parts. The oil tank is bell type and expansion storage. Oil tank, beautiful appearance.

Power Transformer Transport Packaging:

· power transformers are packaged in 20-frame container or one 40 HQ container.

· The transformer body is well fixed with steel wire rope and sleeper, and equipped with an impact recorder.

· The radiator, oil conservator, and other accessories are packed in wooden cases.

· Avoid collisions and keep the shape of the transformer intact.

· Avoid corrosion, rust, etc. caused by environmental factors.
