Pucaro presspaper in rolls

Presspaper is a special product based on the purest cellulose, extracted from long-fibered coniferous trees. These are formed into a non-woven material without using any additional binding agents and then pressed.

Hitachi ABB Power Grids offers Pucaro presspaper with high chemical purity, which is an exceptionally suitable insulation material for electrical machines (impregnated with resin), capacitors (impregnated with oil or resin) and particularly oil-filled transformers. The material properties allow classification in insulation class A (105 °C) and are manufactured in accordance with the IEC 60085 standard.

Depending on the thickness of the material, a distinction is made between Pucaro presspaper in rolls and board material.
