Pressboard knows in different-different countries in different-different
names i.e. Transformerboard, Press Boards, Pressboards, Paperboard,
insulation pressboard, cellulose based board, insulation board,
transformer board etc.
Pressboard is a hard and rigid board having high
purity with excellent electrical and mechanical properties, is specifically
produced for the high voltage and extra high voltage Transformer
Industry. The product is made from virgin softwood sulphate pulp.
Pressboard produces in sheet form in various thicknesses,
various densities and manufacturing methods - calendared, hot-press-dried,
corrugated or laminated structures.
Precompressed Pressboards are cellulose based and
are produced from electrical grade kraft unbleached softwood pulp
having high chemical purity and low conductivity.
They are produced on intermittent board machine and
compacted without added bonding agents in multi day-light press
under heat and pressure to achieve required properties. The boards
are characterized by high density, high purity, uniform thickness,
dimensional stability, low compressibility, low shrinkage and high
electrical strength.
Precompressed Pressboards have high dielectric strength
and find use as insulating material in different types of Power
and Distribution Transformers, Capacitors, Switch Gears etc., in
the form of winding cylinders, spacers, washers, keyway strips.
etc.
Actually pre-compressed pressboard is a board made
by compressing layers of insulation paper together and drying them
through hot hydraulic press.
Raw Material
The main raw martial of transformer board is cellulose
based “electrical grade” unbleached sulphate softwood
pulp.
Application
High Density Pressboard used for Power Transformers
above 132kV Class and Medium Density Pressboard used for Power &
Distribution Transformers and Switchgears below 132kV Class for
electrical insulation purpose.
Pressboard is the base material for components
like cylinders, strips, spacers, rings, washers, plates. Having
control over the many steps of the whole process chain from unbleached
electrical grade pulp to components is advantageous in respect to
product quality, customized solutions and creating value in the
field of application: insulation of high voltage transformers.
