★Material Selection and Procurement
Due to our rich experience in production and manufacturing for power transformer, we have a wealth of selection advantages and price advantages in the selection of raw materials and suppliers. The quality and price of the products are advantages for us.
1.Core Material: Grain-oriented electrical steel is typically selected for the transformer core due to its high magnetic
permeability.
2.Copper/Aluminum Windings: High-conductivity copper or aluminum is chosen for the windings.
3.Insulation Materials: Insulating paper, pressboard, and varnishes are selected based on their dielectric properties.
4.Tank and Enclosure: The materials for the tank and enclosure (usually steel) are selected for durability and corrosion
resistance

★Core Construction
In order to assure the implementation ofthe advance design and manufactural tech-nology,some key equipments,moulds andtools had been repleced,moulds andimprovedwith the new technologies to meetthe requrements of product quality.
1.Core Cutting: The steel sheets are cut into specific shapes and sizes according to the design.
2.Core Assembly: These sheets are stacked together to form the transformer core, usually in a step-lap formation to minimize losses.

★Assembly
1.Core and Coil Assembly: The windings are placed around the core, and the entire assembly is secured in place.
2.Tank Assembly: The core-coil assembly is placed into the transformer tank, and connections are made for input and output terminals.
3.Filling with Insulating Fluid: The tank is filled with an insulating fluid, typically mineral oil, to provide cooling and
electrical insulation.
2.Tank Assembly: The core-coil assembly is placed into the transformer tank, and connections are made for input and output terminals.
3.Filling with Insulating Fluid: The tank is filled with an insulating fluid, typically mineral oil, to provide cooling and
electrical insulation.
★Vacuum Drying
The transformer is placed in a vacuum oven to remove any moisture trapped in the insulation and the insulating fluid. This step is crucial for ensuring the longevity and reliability of the transformer.
★Quality Assurance
A quality control team reviews all test data and inspections to ensure the transformer meets all regulatory and customer-specific requirements.
★Packaging and Shipping
1.Packaging: The transformer is carefully packaged to prevent damage during transport.
2.Shipping: It is then shipped to the customer or the installation site.
