Transformer Pressboard Insulation Block

Transformer Pressboard Insulation Block is a precision-machined solid insulation component made of high-density pure wood pulp pressboard. It features high compression resistance, stable dimensional accuracy and excellent oil immersion resistance. This insulation block is mainly used for winding fixing, spacing and mechanical support of oil-immersed power transformers. It effectively prevents winding displacement and vibration while maintaining safe insulation clearance. Custom special shapes and sizes are available based on customer requirements. High precision and smooth surface.
