Product description

PRESSPAPER  PSP3055

TYPE P 4.1 IN ACCORDING TO IEC 641

PRESS PAPER PB2

ACCORDING TO JIS C 2111

 

Description:

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.

 

Features

●Calendered presspaper, good forming properties, 100 % sulphate pulp 

● Colour natural 

● High purity and high oil-absorption 

● High electric dielectric strength

●Presspaper can be coated with baked enamel or laminated with Polyester Film

●Good compatibility with liquid dielectrics 

 

Applications

As interlayer insulation in liquid-filled transformers, motors

 

Available

Thickness: 0.10mm – 0.50mm

Both in roll and sheet are available

Width: 500mm – 1250mm

Special sizes are available on request
