Insulation Support Strips are vital structural elements within transformers, engineered to secure windings, maintain precise oil duct clearances, and enhance thermal management. Their design is crucial to the transformer’s mechanical strength, cooling performance, and insulation integrity.

Applications and Functions of Insulation Support Strips:

★Oil-Immersed Transformers:

Winding Fixation: Work together with upper and lower positioning rings and columnar spacers to create a robust mechanical support system, preventing winding short circuits or deformation.

Cooling Optimization: The spacing between insulation support strips directly influences oil flow. Elongated hole designs (e.g., 20–30 mm spacing, 5–8 mm diameter holes) increase the heat dissipation surface area.

★Dry-Type Transformers:

Utilize high-temperature-resistant materials (e.g., Class F, 155°C) to avoid softening or deformation under thermal stress.

★Special Scenarios:

High-Humidity Environments: Employ anti-hygroscopic materials such as polyimide composites.

High-Frequency Transformers: Optimized dielectric properties help minimize partial discharge risks.

These insulation support strips can also be used to make Transformer Ladder Duct Struct
