Crepe Paper Insulation
Crepe Paper Insulation Introduction
Insulation Crepe Paper is one of the electrical insulation paper. It is made of 100% superior sulfate insulating wood pulp. It has good dielectric strength, excellent compatibility with insulating liquids (mineral oils, silicone oils, and acerola oils), and free from conductive particles. Electrical grade insulation papers are 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

Crepe Paper Insulation Features
1. High purity and high oil-absorption
2. Good dielectric strength
3. Excellent compatibility with insulating liquids (mineral oils, silicone oils, and acerola oils).
4. Free from conductive particles
Crepe Paper Insulation Application
It 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.
