Presspaper PSP 3055

P.2.1B according to IEC 60641-3-2

• PSP 3055 is a natural-coloured, calendered presspaper made of 100 % unbleached sulphate

cellulose that is free of all bonding agents.

•  PSP 3055 is manufactured in thicknesses from 0.10 to 1.0 mm and is primarily used for core

insulation, layer insulation and winding insulation on distribution transformers.

•  Upon request, the presspaper PSP 3055 can also be provided in a special “Thermally upgraded”

version (name: Presspaper PSP 3055 TU). Here the thermal ageing process of the presspaper is

delayed by adding a small quantity of a nitrogenous additive.

Presspaper PSP 3055 SL

P.4.1A or P.4.1B* according to IEC 60641-3-2

• PSP 3055 SL is a natural-coloured, calendered presspaper made of 100 % unbleached sulphate

cellulose that is free of all bonding agents, similar to the presspaper PSP 3055. In contrast to the

presspaper PSP 3055, however, it has a lower density. For this reason, the capacity for impregnation with fluid dielectrics is improved, which results in shorter impregnation times, greater

absorption capacity and greater electric stability after impregnation. But a certain reduction in

tensile strengths should be expected.

• Upon request, the presspaper PSP 3055 SL can also be provided in a special “Thermally upgraded”

version (name: Presspaper PSP 3055 SL TU). Here the thermal ageing process of the presspaper is

delayed by adding a small quantity of a nitrogenous additive.

• PSP 3055 SL is manufactured in thicknesses from 0.05 to 0.50 mm and is primarily used for core

insulation, layer insulation and winding insulation on distribution transformers, as well as in

capacitors.

Presspaper, two-layer bonded PSP 3055-2

Similar to P.2.1B according to IEC 60641-3-2

• The two-layer presspaper PSP 3055-2 is a natural-coloured, calendered presspaper made of 100% unbleached sulphate cellulose, which has been bonded with

an adhesive for the added electrical safety of two layers of presspaper PSP 3055.

• Presspaper PSP 3055-2 is manufactured in thicknesses from 0.10 to 0.25 mm

and is primarily used for layer insulation and winding insulation on distribution

transformers. With the two-layered bonding, lower material thicknesses with

sufficient electrical stability are possible - and as a result transformer coils can

be built smaller and more compact.

• Upon request, the presspaper PSP 3055-2 can also be provided in a special

"Thermally upgraded" version (name: Presspaper PSP 3055-2 TU). Here the

thermal ageing process of the pressboard is delayed by adding a small quantity

of a nitrogenous additive.
