Precompressed boards are produced from 100% pure and unbleached softwood sulphate pulp. The main properties of this material are its high chemical purity and low conductivity. The process involves dehydration, compression, and drying – all performed in a special hot press. Precompressed boards score very high in mechanical and electrical strength and offer dimensional stability, low compressibility, and shrinkage.
Applications
Precompressed boards are ideally suited for use in the cylinders, plates, washers, and supports of power and distribution transformers.
