Descreption:
Transformer electrical Press board/ Paperboard/ Cardboard/ Pre-compressed Board is made with high grade unbleached Sulphate wood pulp, having characteristics of high mechanical strength, electrical strength, tensile strength, high elongation, low compressibility and proper bending resistance. Used in oil filled transformers as an insulation barrier between HV and LV windings and the winding end area which can increase the electricalstrength of the oil.
