Boreviax coordinates overseas sales, specification confirmation, export delivery and after-sales service for the authorized insulation manufacturer.

Material selection

Select the product according to its function in the transformer

Laminated pressboard is used where dielectric performance and greater structural support are required. Corrugated pressboard is formed to create controlled oil paths and oil-gap structures. Diamond dotted insulation paper supports interlayer bonding during drying and heating, while thin insulating paper and crepe paper are used for wrapping and flexible insulation duties.

Material grade, thickness, width, dimensions, roll format, processing requirements and applicable tests are confirmed according to the customer specification and order.
