Product introduction:
Crepepaper tube is commenly used in transformers. It is made of electrical crinkled insulating paper through special process, is mainly used as insulating package material inside oil-immersed transformers. Our crepepaper tubes are fully achieved by automatic machine. It has standard inner and outer diameters, and we can also desigh crepepaper in different diameters and wall thickness to meet customer's demands.
