Aramid insulating paper

Insulation materials are divided into solid insulation materials, liquid insulation materials and gas insulation materials. Paper as a solid insulation material for electrical equipment has a long history and is widely used in cables, coils and other electrical equipment.

Due to the special purpose of insulating paper, it must have some characteristics different from other paper grades, mainly including mechanical properties, electrical properties and thermal stability. Mechanical properties mainly include tensile strength and elongation at break; Electrical properties mainly include dielectric strength, dielectric constant, dielectric loss, resistivity, etc.

According to the different raw materials for preparation, insulating paper can be divided into three categories: plant fiber paper, mineral fiber paper and synthetic fiber paper. Among them, synthetic fiber paper represented by aramid insulation paper is the most convenient and successful.
