Crepe Paper is made of 100% sulphate wood pulp wet-copying, with undried flat network base paper through the wrinkling process and it has the advantages of good softness, not easy to break by bending, good elongation, good oil absorption and so on.Crepe Paper is widely used in oil-immersed transformers, instrument transformers, reactors and other parts of package insulation, especially as lead parts of the insulation package, thereby improving the electrical insulation and mechanical properties of the product structure.
Excellent Elongation and Flexibility:
The creped structure provides outstanding stretchability and bending adaptability, making it ideal for wrapping complex and irregular-shaped components.
High Oil Absorption and Impregnation:
The crinkled surface increases the contact area, allowing it to retain more insulating oil, which helps improve transformer heat dissipation and overall insulation performance.
High Electrical Insulation Strength:
Offers excellent dielectric properties, capable of withstanding high operating loads and thermal stress.
High Purity:
Made from insulating-grade wood pulp, ensuring stable electrical performance and minimal reactivity in humid environments.
Transformer Manufacturing:
Widely used as a primary solid insulation material in oil-immersed transformers for interlayer insulation, lead insulation, and end insulation.
Cable Industry:
Applied in high-voltage cables for shielding and insulation wrapping.
Special Customization:
Black insulating crepe paper is used in applications requiring semi-conductive shielding.
