The customization process for 110KV and 220KV large transformers is a complex and intricate process that covers multiple stages from requirement analysis to product delivery. The following is a general customization process:

Definition:A power transformer is a static device that transforms electrical energy between two or more circuits through electromagnetic induction. It consists of two or more coils of insulated wire wound around a core made of magnetic material. The primary coil receives electrical energy at one voltage level, and the secondary coil delivers it at a different voltage level.

Core: Usually made of laminated iron or steel, the core provides a low-reluctance magnetic path for the transformer. It enhances the efficiency of energy transfer by minimizing magnetic flux leakage.

Windings: The primary and secondary coils, or windings, are insulated conductors wound around the core. The number of turns in each winding determines the voltage ratio between the input and output.

Insulation: To prevent electrical breakdown and ensure the safe operation of the transformer, insulating materials such as oil-impregnated paper, pressboard, and synthetic materials are used.

Tank: The transformer is housed in a tank filled with insulating oil to dissipate heat generated during operation and to provide additional insulation.

Functionality: Step-up and Step-down Voltage Transformation:Step-up Transformer: Increases the voltage from the primary winding to the secondary winding.Step-down Transformer: Decreases the voltage from the primary winding to the secondary winding.

Power Transfer: Transforms electrical power at a specific voltage and current level in a way that minimizes energy losses.

Isolation: Provides electrical isolation between the primary and secondary circuits for safety and to avoid ground loops.

Distribution Transformers: Used in distribution networks to supply lower voltage to end-users.

Power Transformers: Used in power transmission systems to step up or step down voltage levels over long distances.

Instrument Transformers: Designed for use in measuring instruments and protective relays to scale down high voltages and currents.
