Product/Technical Imformation

Transformer board (T.B.) is a laminated electric insulator made from extremely pure craft pulp. Superior electrical and mechanical characteristics make it ideal for insulating ultra-high voltage large-capacity transformers. When durability is essential, our major brand high-density paper is molded into winding cylinders and spacers and processed into press rings after being glue-laminated. Molded products of complex configurations are hand made using wet sheets.

Our high-quality transformer board is indispensable in 1 million volt transmission lines to ensure low transmission losses.
