Electrical grade insulation paper is a type of paper that is specifically designed for use as insulation in electrical applications. It is made from a combination of high-quality wood pulp and other insulating materials, which provide it with excellent insulating properties and high dielectric strength. Electrical grade insulation paper is commonly used in the manufacture of transformers, motors, generators, and other electrical equipment where high voltage and current are present. It is available in various forms such as rolls, sheets, and strips, and is usually rated according to its thickness, density, and other properties such as temperature resistance and moisture resistance.
