The impregnated insulating paper is an insulating paper for impregnating the laminate after impregnating the resin. According to the use of the laminate, the impregnated insulating paper is divided into sulphate wood pulp paper and sulfite wood pulp paper. Impregnated insulating paper is the biggest characteristic is a good impregnation, the height of its absorption is the highest insulation paper, impregnated insulating paper was neutral.
Insulated crepe paper
Insulated crepe paper is made of electrical insulation paper by creping. Wrinkles in the transverse direction, wrinkles are pulled when stretched. Due to the different wrinkle processing procedures, wrinkled paper with different elongation can be made. Insulating paper thickness is generally 0.05mm ~ 0.12mm, elongation range of 5% to 200%. Insulated crepe paper is often used in oil-immersed transformers, such as windings, wire and insulation screens.
