Product description of insulation paper
Presspaper PSP3055 and Press Paper PB2 is a special product on the basis of the purest wood cellulose fibres. Without any additional binding agents, these are made up into a fibrous web and then pressed. Due to its high chemical purity, presspaper PSP3055 and Press Paper PB2 is particularly suited as an insulating material in electric machines, capacitors, motors, etc., and especially in oil-cooled transformers. Where can we use the product? Product application will make us a direct impression. Product Application of insulation paper
As interlayer insulation in liquid-filled transformers, motors
