What is impregnated insulating paper?

The impregnated insulating paper is an insulating paper for pressing the laminated product after impregnating the resin. The impregnated insulating paper is divided into a sulphate wood pulp paper and a sulfite wood pulp paper according to the use of the laminate. Impregnated insulating paper is the biggest feature is a good impregnation, the height of its absorption is the highest insulation paper, impregnated insulating paper was neutral.
epoxy glass laminate sheet is made of electrical insulation paper by creping. Wrinkles in the transverse direction, wrinkles are pulled when stretched. Due to 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%. glass fiber sheet is often used in oil-immersed transformers, such as windings, wires and insulation screens.
