Overview of the Production Process

  1. Raw Material and Semi-finished Product Management

The first step in the production line is the management of raw material and semi-finished product storage and logistics. This often involves automated warehousing systems and material handling equipment, such as AGVs (Automated Guided Vehicles) and RGVs (Rail Guided Vehicles), to ensure efficient flow of materials and semi-finished products.

  1. Inner Mold Assembly

In the inner mold assembly stage, automated equipment assembles the core and windings according to preset process designs. This step is crucial for ensuring the structural stability and electrical performance of the transformer.

  1. Winding

Winding is a key step in the manufacture of dry type transformers, involving the precise winding of conductors around the core according to specific design requirements. This process is typically carried out by numerical control winding machines to ensure accuracy and consistency.

  1. Outer Mold Assembly and Potting

After winding, the outer mold is assembled, and the potting process is carried out. This step may involve using epoxy resin or other insulating materials to pot the windings, enhancing their insulating properties and mechanical strength.

  1. Curing and Demolding

After potting, the transformer needs to go through a curing process to ensure that the insulating materials are fully hardened. After curing, the mold is removed, revealing the completed transformer.

  1. Winding Cutting and Grinding

Winding cutting and grinding are subsequent processing steps used to trim the edges of the windings, ensuring the appearance and electrical performance of the transformer.

  1. Final Assembly

Once all components are ready, the transformer undergoes final assembly, including connecting leads, installing insulating parts, and the casing.

  1. Factory Testing and Inspection

Completed transformers undergo a series of factory tests and inspections, including electrical performance tests and insulation strength tests, to ensure that the products meet quality standards and customer requirements.
