1. Main Uses

Transformer Winding Insulation
Due to its unique creping feature, crepe paper can be stretched when used, making it very suitable for insulating the windings of transformers. Typical applications include insulation for winding terminals, leads, and static rings.

2. Performance Characteristics

High Mechanical Strength
Crepe paper has high mechanical strength, allowing it to withstand various mechanical stresses during transformer operation, ensuring the integrity and reliability of the insulation layer.

Good Electrical Performance
Crepe paper has excellent electrical properties, including dielectric strength and insulation resistance, effectively preventing electrical breakdown and leakage.

Good Heat Resistance
Its heat resistance allows crepe paper to maintain stable insulation performance in high-temperature environments, meeting the operational requirements of transformers.

3. Specific Application Scenarios

Winding Insulation
During the manufacturing of transformer windings, crepe paper is used for inter-turn and inter-layer insulation to prevent electrical breakdown and short circuits between windings.

Lead Insulation
Leads passing through the transformer oil tank or windings need to be insulated with crepe paper to prevent electrical contact with other components.

Static Ring Insulation
The static ring, which is used to eliminate static electricity, also commonly uses crepe paper for insulation.

4. Usage Considerations

Choose Appropriate Crepe Paper
Select the appropriate type and specification of crepe paper based on the specific operational conditions and insulation requirements of the transformer.

Proper Installation
During installation, ensure that the crepe paper is tightly wrapped, free from wrinkles and damage, to guarantee insulation effectiveness.

Regular Inspection
Regularly check the insulation performance of the transformer to promptly identify and address issues of aging or damage in the insulation layer.

Crepe paper plays a significant insulating role in transformers, and its excellent performance characteristics and wide application scenarios make it an indispensable insulating material in the manufacturing process of transformers.
