Product Description

Brief Intruduction
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.

Machined products
Top & Bottom pressure ring, Pressure Beams, core to coil packing, Lead & Cleat support, step block or core packing, Densified wood support, Fasteners & other items for Power & Distribution Transformers.
