The most common high voltage transformer type are Dry Type and Oil-immersed Type. Today let’s talk about transformer advantages, disadvantages and differences.
Oil Immersed Transformer:

Oil Filled Transformer have two types:
1.Corrugated Fins Wall Cooling Type
2. Radiators with Cooling Fans
Corrugated Fins Wall is made by SPCC steel roll by folding, forming and welding method. JTFY Full Auto Corrugated Fins Wall Manufacturing Line consists of: Steel Coil Feeding-Hydraulic Decoiler, Auto Steel Folding& Forming Machine, Auto Corrugated Fins Seam Welding Machine, And Leakage testing Machine.Which make the Complete Production of Corrugated Fins Wall automatically.

Transformer Advantages and disadvantages of dry-type transformer and oil-immersed types:
1.Dry-type transformer is more expensive than oil in price.
2.In Capacity, large capacity oil changes more than dry capacity.
3.Dry transformations are required in complex buildings (basements, floors, roofs, etc.) and crowded places. Oil transformer is used in independent transformer substation.
4.The transformer inside the box transformer usually adopts the Dry-type transformer. Outdoor temporary electricity is usually changed by Oil type transformer.
5.Dry type and Oil type Transformers can be selected according to space during construction. Oil type can be selected when space is large, and Dry type can be selected when space is crowded.
6.Regional climate is humid and muggy areas, better to use oil type transformer. If dry type is used, forced air cooling equipment must be equipped.
