ENPAYBOARD® is a high-quality insulating pre-compressed pressboard made of cellulose, characterized by its high chemical purity and permanent heat stability. The pulp used in ENPAY BOARD® is pure, free of impurities, and has exceptionally low shive levels.
ENPAYBOARD®, a hard and rigid board with high purity and excellent electrical and mechanical properties, is specifically manufactured for the High Voltage and Ultra High Voltage Transformer Industry, with applications up to 1200 kV, as well as for HVDC Applications. The product is crafted from electrical-grade virgin softwood sulfate pulp using state-of-the-art technology in our production line. Separate conditioning and testing facilities have been established for uninterrupted and efficient testing and evaluation of the raw materials and the product.
ENPAYBOARD® is produced on an intermittent board machine and compacted without the addition of bonding agents in a multi-daylight press under heat and pressure to achieve the required properties. These boards are characterized by their high density, purity, uniform thickness, dimensional stability, low compressibility, low shrinkage, and high electrical strength.
ENPAYBOARD® exhibits high dielectric strength, making it suitable for use as insulating material in various types of Power and Distribution Transformers, Shunt Reactors, Capacitors, switchgears, etc., in the form of winding cylinders, spacers, washers, keyway strips, etc. ENPAY offers a comprehensive range of electrical pre-compressed products under the brand names ENPAYBOARD E3 and ENPAYBOARD® E4.
These two main product grades satisfy a wide range of insulation performance requirements for power and distribution transformers.
