Product Description

Pre-compressed PressBoard for Transformer insulation

Since the invention of high voltage electrical transformers, there has always been a need for an insulating material that could withstand high electrical and physical stress exerted on core and windings.

Transformer Board is a type of paperboard with high basis weight made from low conductive virgin wood pulp cellulose, and works as the base material for transformer insulation structure parts like cylinders, strips, spacers, rings, washers, plates, machine formed and molded parts, punching and laminates.

Insulation class A (105 °C)
Calandered Pressboard, 100% sulphate pulp
High Flexible and Soft
Low shrinkage and compatibility
High purity and mechanical strength
Good compatibility with liquid dielectrics
Further processing is ensured since the pressboard can be punched, folded,cut and formed without difficulty.

To use as insulations material in Power and Distribution Transformers.
It is the base material for components like corrugated boards, cyclinders, rings and mouldable parts.

Transformer Board

Transformer board is made by Aspa and Prince George's 100% e-grade non-bleached sulphate coniferous wood pulp from Sweden and Canada. High quality raw material makes products with good performance characteristics, such as its higher mechanical and electrical strength,higher tensile strength, lower compressibility and better bending performance, power transmission and transformation equipments.

Laminated Pressboard

Laminated pressboard is produced by laminating and pressing of multi-layers of high-quality transformer board together with phenolic resin,casein glue and polyes of adhesive.comparing with laminated wood, laminated board has the advantages of higher density,better mechanical strength,higher electrical strength and lower compressibility, better insulation property strength.
