1. DescreptionIt is made of 100% superior sulfate insulating wood pulp. It has Good dielectric strength, Excellent compatibility with insulating liquids (mineral oils, silicon oils and ascerol oils) and Free from conductive particles
.
2.Specifications 1). Insulation materials
2). 100% wood pulp
3). 50% flexibility
4). Thickness: 0.35-0.90mm
5). Insulation class A (105 °C)
3 Application Crepe Papers are suitable for irregular shapes and surfaces where normal insulation materials failes to reach, used in magnet wire, layer, current transformers, RIP bushings or as shielding material
Insulation crepe paper is made of electrical insulation power cable paper made by 100% superior sulfate wood pulp. It has high dielectric properties, good elongation, etc. Insulation crepe paper is widely used for winding and binding the parts in oil immersed transformers, current transformers, reactors, etc.
