The crepe paper tube is a high-quality insulating product used extensively in transformers, motors, switchgear, and other electrical apparatus. Manufactured from pure cellulose crepe paper, this flexible tube offers excellent dielectric strength, conformability, and oil absorption properties, making it ideal for wrapping and insulation in oil-filled electrical equipment.

Its corrugated surface enhances mechanical flexibility and surface area, which improves oil retention and insulation reliability. Crepe paper tubes are commonly used for insulation of transformer leads, connections, and other components where high flexibility and insulation performance are essential.
