Calendered Solid Pressboards are made on an intermittent board machine using high quality cellulose. The boards are flattened in a hydraulic press, dried, and subsequently calendered to achieve a smooth finish. No bonding agent is added during manufacturing. The entire manufacturing process is monitored and controlled, right from the preparation of pulp to the formation and drying of the sheets. Calendered Solid Pressboards are ideally suited for use in power and distribution transformers as winding cylinders, spacers, strips, etc.

Pre-Compressed Pressboards 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 Pre-Compressed Pressboards are ideally suited for use in the cylinders, plates, washers, and supports of power and distribution transformers. Features Conforms to the electrical and mechanical strength properties as specified by IEC 60641-3-1: Type B.3.1A. Available in 1.0, 1.5, & 3.0 mm thickness in stock, and other thickness on request. High density and purity, uniform thickness and dimensional stability, low compressibility & shrinkage, high mechanical & electrical strength.
