Advantages and Disadvantages between Dry & Oil immersed type High Voltage Transformer

The most common types of high voltage transformer are Dry Type and Oil-immersed Type. Today let’s talk about their advantages and disadvantages and differences.

Oil Immersed Transformer:

Oil Filled Transformer have two types: Corrugated Fins Wall Cooling Type & 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.

Advantages and disadvantages of dry-type transformer and oil-immersed transformer:

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.

How to choose Distribution Transformer?

The Key Selection points of Oil-Immersed Distribution Transformer . Load Properties of Distribution Transformer: 1) When there are a large number of primary or secondary loads, it is advisable to install two or more transformers. When one transformer is disconnected, the capacity of the remaining transformers can meet the demand of primary and secondary loads. First, the secondary loads should be concentrated as far as possible and should not be too dispersed. 2) When seasonal load capacity is large, special transformer should be installed. For example, in large civil buildings, the load of air conditioning refrigerators, heating electricity and heat, etc. 3) When the concentrated load is large, special transformer should be installed. Such as large heating equipment, large X-ray machine, electric arc furnace, etc. 4) When the lighting load is large or the power and lighting use common transformer seriously affects the lighting quality and lamp life, special lighting tra
