Electrical insulating crepe paper
Electrical insulating crepe paper is wet lapped the 100% sulfate wood pulp,then wrinkle the base insulating paper which hasn’t dried.The electrical insulating paper is flexible,with high elongation and high oil absorption properties.It’s widely used as turn insulation,CTC and layer insulation in transformers,reactors and mutual inductors.
Recommended width: 700mm、1100mm,we can also slit it to be belts. Tailor-made by customers’ requirements is available.
Storage
The product should be stored in dry, clean and well-ventilated warehouse. The fire, heat sources and direct sunshine should be avoided.
