Transformer Manufacturing Materials

Transformer Manufacturing Materials: Which is the best?

On behalf of modern machinery and equipment systems, it also depends on input materials to have a good transformer. Materials for manufacturing transformers are always strictly controlled by manufacturers, ensuring suitable quality, quantity, and type under domestic and international standards.

To learn materials for transformer manufacturing, we first need to know about the structure of the transformer. The general basic construction of the transformers (or parts of the transformer) has three parts: steel core, coil, and machine cover.


Steel core: used to conduct flux, made of good magnetic conductive materials. Transformer cores are laminated to reduce eddy current loss. Consists of many thin steel sheets (another word that is laminated core), the outer surface with insulating paint are assembled into the steel core. The steel core consists of 2 parts, including Pillar and Gong.

Coil: used to receive energy in and transmit energy out. Usually made of copper or aluminum, the cross-section is circular or rectangular and insulated. The number of turns of the two coils varies, depending on the transformer duty.

Machine cover: The case types depend on the kind of transformer but is usually made of steel or thin sheet, which is used to protect the internal components. The case includes the barrel and lid. 

  • The barrel enhances insulation and heat dissipation.

Consists of many thin-rolled electrical engineering steel sheets

Good electrical conductivity, limiting oxidation, increasing durability, the longevity of the machine and reducing energy consumption

The price is 3-time more than Aluminum Coil







Conductive electricity is only 60% of copper coil, the criteria for durability, power consumption, the longevity of the machine is also lower than copper wire one. Aluminum wire is reduced by more than 30% by weight compared to copper wire.





The highest price, the heaviest cover. In return, the machine is protected at the maximum.






Prices are average, lighter than steel cases.

Ability to protect the machine at a good level.
