S22 Oil immersed distribution transformer

S22 oil immersed distribution transformer, compared with ordinary oil spill transformer, cancels the oil conservator and uses the wave fin of corrugated oil tank instead of oil pipe as the cooling and radiating element. The corrugated oil tank is made of excellent cold-rolled steel sheet on the special production line. The wave fin can expand and contract with the increase and contraction of transformer oil volume, so as to isolate the transformer from the atmosphere and prevent and slow down the deterioration of oil and insulation moisture, Enhance the reliability of operation and avoid maintenance during normal operation. It is suitable for anti rust (anti rust) and anti rust (anti rust) paint on the surface of oil tank after phosphating and petrochemical treatment.
