Electrical insulation paper is one of the basic materials used in the production and regeneration of electrical devices. This material is used to insulate conductive elements in electric motors, transformers, generators, and other electrotechnical devices.

The most commonly used materials include electrical insulation pressboard and Kraft paper. Pressboard is made from pressed cellulose fibers and is characterized by high mechanical strength and very good dielectric properties. Kraft paper, on the other hand, is a thinner and more flexible material, mainly used as insulating spacers between winding layers.

These materials are primarily used in slot insulation and as electrical insulation spacers in electric motors and transformers. Due to their good insulating properties and temperature resistance, electrical insulation paper is an important element of insulation systems in the electrotechnical industry.
