ENPAYBOARD® is high-quality insulating pre-compressed pressboard made from cellulose, of high chemical pureness and permanent heat stability. The pulp used is pure, free of dirt and has exceptionally low shive levels.

ENPAYBOARD®, a hard and rigid board having high purity with excellent electrical and mechanical properties, is specifically produced for the High Voltage and Ultra High Voltage Transformer Industry up to 1200 kV as well as for HVDC Applications. The product is made from  electrical grade virgin softwood sulphate pulp in our production line using "state of the art technology". Separate conditioning and testing facilities have been established for uninterrupted and speedy testing and effective evaluation of the raw materials and the product.

ENPAYBOARD® is produced on an intermittent board machine and compacted without added bonding agents in multi day-light press under heat and pressure to achieve required properties. The boards are characterized by high density, high purity, uniform thickness, high dimensional stability, low compressibility, low shrinkage and high electrical strength.

ENPAYBOARD® has high dielectric strength to be used as insulating material in different types of Power and Distribution Transformers, Shunt Reactors, Capacitors, Switch Gears etc., in the form of winding cylinders, spacers, washers, keyway strips, etc.

ENPAY offers a comprehensive range of electrical pre-compressed pressboard products under the brand names ENPAYBOARD® E3 and ENPAYBOARD® E4. Two main product grades satisfy a wide range of insulation performance requirements for power and distribution transformers.
