Insulation crepe paper for transformer is made of insulating Kraft paper with creping. It has very good oil-soluble properties, and is widely used in oil-immersed transformers, instrument transformers, reactors and other parts of package insulation, especially as lead parts of the insulation package, thereby improving the electrical insulation and mechanical properties of the product structure.
Insulation Crepe Kraft Paper
Wood Pulp
High Temperature
0.05mm, 0.075mm, 0.13mm and more
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, excellent compatibility with insulating liquids (mineral oils, silicon oils and ascerol oils) and it’s free from conductive particles.
● 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. It is widely used for winding and binding the parts in oil immersed transformers, current transformers, reactors, etc.
