Oil immersed distribution transformer

oil immersed transformer Performance characteristics

•Unique Welding Process, No Leakage

Eliminate the high and low pressure risers to reduce welds; the fuel tank wall uses wide-width steel plates to reduce joints; a unique welding process to ensure welding quality.

•Groove Structure

All sealing flanges are grooved to ensure sealing performance.

•Control Leakage

All the oil drain valves of the transformer are made of copper valves, and the radiator uses a vacuum butterfly valve to reduce the leakage of the transformer.

•Low Loss, Low Noise

Adopt domestic and foreign advanced technology and equipment, professional research and development. The core adopts high-performance cold-rolled oriented silicon steel sheet and fully automatic robot lamination machine with small shear burr and low lamination coefficient, which effectively reduces the no-load loss, no-load current and noise of the transformer. The no-load loss is 5% to 15% lower than the manual lamination.
