How should the toroidal transformer coil be fixed?

For coil fixation of toroidal transformers, a common method is to use insulating materials and support structures to secure the coils. Here are some common ways to secure coils:

1. Insulating materials: Use insulating materials, such as insulating paper, insulating tubes or insulating tape, to insulate and wrap the coils and at the same time fix the coils. This method provides good insulation and mechanical support to prevent coil movement during vibration or operation.

2. Support structure: Use a support structure to secure the coil, such as a metal or plastic clamp, bracket or shelf, etc. The support structure can be designed as a ring or a line as needed to accommodate the shape and size of the coil. The support structure is usually connected to other parts of the transformer to ensure the stability of the coil during use.

3. Adhesive: Sometimes, a special adhesive or glue can be used to secure the coil. This provides a strong bond after curing, ensuring coil fixation and stability. However, care needs to be taken to select a suitable adhesive to ensure its stability and durability under high temperature and pressure conditions.
