Huisheng Group is a professional manufacturer of pre-compressed pressboards, insulation molded components, core boards and paper tubes in China. We are the biggest core board manufacturers and one of the largest manufacturers of transformer pre- compressed pressboards in China. Our transformer pressboards are made of electric grade unbleached sulphate wood pulp, with characteristics of high mechanical, electrical strength, tensile strength, high elongation, low compressibility and proper bending resistance. With excellent properties, our products have wide-spread application in electrical transmission and distribution equipment like power transformers, shunt reactors and instrument transformers. Our core board product has been widely applied to high duty cores, textile bobbins and industrial tubes for paper-making and plastic films. Our core board can completely replace imported high grade core board. Moreover, we can supply slitted coils according to customer requirements.
