Product description of wood iso9001 insulation pressboard sheet
Pressboard PSP3052 (Transformer Board PSP3052) is a special product based on pure cellulose taken from long-fibred coniferous wood. This is structured into a fibrous tissue without additional adhesive and then pressed. Due to its high chemical purity, pressboard is excellently suited as an insulation material in electric machines, capacitors and oil-filled transformers.
