Crepe Paper for Transformers Electrical Insulation Material
1). Insulation materials
2). 100% wood pulp
3). 50% flexibility
4). Thickness: 0.35-0.90mm
5). Insulation class A (105 °C)
6). Standard Color: natural
Crepe Paper is suitable for irregular shapes and surfaces where normal insulation materials fail to reach, used in magnet wire, layer, current transformers, RIP bushings or as shielding material
The insulating crepe paper is wrapped on the transformer, transformer and high-voltage cable to protect the insulating layer of the conductor wire and avoid damage to the insulating layer. It is widely used in the use of transformers, transformers, reactors, electromagnetic wires and high-voltage cables. Different widths can be customized according to customers
Delivery Form: width 14~ 850mm
Length: base on request
