Product Description

Electrical Transformer Insulation Pressboard for Oil-filled Transformers&Capacitors
Product Description

Our Transformer Insulation Pressboard is a high-performance dielectric material essential for the insulating structure of transformers and other power transmission equipment.  Made from pure, unbleached cellulose fibers derived from long-fibered coniferous wood, it offers high chemical purity, excellent oil impregnability, and reliable mechanical strength.  With outstanding dielectric properties and thermal stability, it effectively prevents electrical breakdown and ensures long-term durability.  Primarily used in oil-filled power transformers and distribution transformers, it is also widely applied in electric machines, capacitors, and switchgear, providing essential insulation and protection for high-voltage applications.
