Electrical pressboard

Product Features：

Press board has high mechanical strength, appropriate thickness, density and moisture. It is also highly flexible and applicable.

Pre-compressed pressboard


         Transformer pressboards are made with pre-compressed grade unbleached sulphate wood pulp, with characteristics of high mechanical, electrical strength, tensile strength, high elongation, low compressibility and proper bending resistance.The excellent properties realized wide-spread application in electrical transmission and distribution equipments like power transformers,shunt Reactors,instrument transformers.etc.

product advantage


        High mechanical and electric strength ※Uniform clear color
        Uniform thickness, stable density and moisture content, good elongation and evenness.
        Excellent flexibility, strong applicability.
        Little shrinkage
        The density deviation along CD direction of each single layer wet paper sheet must be controlled within the limits±1.5% comparing with the standard
        Ability of producing 8mm transformer pre-compressed pressboard continuously.

quality promise
