Presspan is a product made from the cellulose of the purest, long-fiber woods. This is formed into a fiber fleece and then pressed. Due to its high chemical purity, pressed wood is used particular as an insulating material in electrical machines (resin-impregnated), capacitors (oil- or resin-impregnated) and especially in oil-filled transformers. The material properties allow classification in insulation class A (105\u00b0C) and are manufactured in accordance with the IEC standard. Depending on the thickness of the material, a distinction is made between sheet and roll pressboard.<\/h5>\n
