Electrical Insulation Crepe Paper is widely used for transformer and motor winding insulation, offering high elongation, excellent flexibility, and reliable dielectric strength. Made from 100% sulfate insulating wood pulp with controlled creping technology, it easily conforms to tight winding, curved surfaces, and layered insulation structures.
Compared with standard insulation kraft paper, crepe paper provides better cushioning and stretchability for coil wrapping, interlayer insulation, and oil duct spacing in both dry-type and oil-filled electrical equipment. Custom slit widths, roll lengths, and die-cut parts are available with fast delivery and small MOQ.
