In this initial stage, suppliers must ensure that materials meet specific quality standards, as these directly influence the performance and durability of the transformers.

2. Core Forming

The core is critical in determining the transformer’s efficiency. The manufacturing process generally includes:

• Lamination Cutting: Thin sheets of electrical steel are cut and laminated to form the core. The lamination design—mitre, butt-lap, or step-lap—depends on the transformer’s specifications and intended application.
• Coating: Each lamination is coated with an inorganic high-resistance layer to minimize eddy currents, which can cause energy losses.
• Assembly: The laminations are stacked and assembled under uniform pressure to maintain structural integrity while minimizing mechanical stress.

Buyers should inquire about the lamination thickness and quality, as these factors significantly affect core loss and transformer performance.

3. Winding

The winding process involves:

• Wire Selection: High-conductivity copper or aluminum wires are selected based on the application requirements. Insulation materials are applied to prevent short circuits.
• Coil Winding: The wires are wound onto the core in a precise manner to ensure optimal performance. This may involve using automated winding machines to maintain consistency.
• Drying and Impregnation: After winding, the coils are dried in an oven and impregnated with insulating oil to enhance dielectric strength and thermal conductivity.

B2B buyers should ensure that suppliers use advanced techniques for winding to enhance the reliability and efficiency of the transformers.

4. Assembly and Sealing

This stage focuses on bringing together all components:

• Tank Construction: High-quality mild steel is used to construct the transformer tank. The thickness and welding standards must meet rigorous quality benchmarks to ensure structural integrity.
• Sealing: Tanks are sealed using neoprene-bonded cork gaskets to prevent oil leakage.
• Cooling Systems: Depending on the transformer type (ONAN, ONAF, or OFWF), appropriate cooling systems are integrated to manage temperature and improve performance.

Buyers should confirm that the assembly process adheres to international standards to guarantee the safety and efficiency of the transformers.

5. Finishing

Finishing processes are essential for protecting the transformer:

• Surface Treatment: All external surfaces undergo sandblasting and are coated with zinc chromate primer followed by two coats of weather-resistant paint.
• Oil Filling: The insulation oil used must meet specific viscosity and dielectric strength standards, ensuring it effectively cools and insulates.

Proper finishing not only enhances aesthetic appeal but also prolongs the life of the transformer under various environmental conditions.
