Description
Densified woodboard is widely used as insulation and supporting material in oil-type transformers and instrument transformers.  It can replace steel plate, insulating pressboard, epoxy paper sheets, epoxy paperboard woven glass fabric lamination in these fields.

Characteristic
Good Electrical Insulation Properties.
High Mechanical strength at Low specific density.
Excellent dielectric properties.
Aptness to work at high temperature.
Very good oil absorption.

Manufacturing process
After being cut to size, each individual piece of veneer is impregnated with phenolic resin in a vacuum autoclave. Following impregnation, the pieces of veneer are baked in an oven to achieve a "B-stage" (partially cured) condition. The next step is to arrange and to stack the veneers to the desired configuration and thickness. Lamination, densification and complete curing are accomplished simultaneously in specially designed hot press machine.
We process all common grades of synthetic resin-compressed wood according to DIN 7707, IEC 61061 using constituents such as selected peeled veneers of beech and special synthetic resins. By impregnation or pressing under high pressure and temperature, a homogenous material is created with excellent technical properties. Different product qualities can be achieved by varying the material structure, resinification and compaction.
