Electrical Insulating Presspaper Grade 3

This grade was developed in co-operation with the power transformer industry, to meet the special needs of manufacturers for a major insulation material which provides an optimum combination of electrical and mechanical strength, stability, low permittivity and maximum oil absorption. The paper is suited for layer insulation, high to low wraps, lead exit protection, petalled ends, layer end packing and can be readily creased and formed in to interlayer wraps with folded edges.
