Description
Plywood is produced by gluing together, in high temperature (145-150ºC) and under high pressure (6-12 MPa), beech veneers 2 mm thick bonded with special phenol-formaldehyde resin. Structure of transformer plywood can be crossed when the grain in neighbouring layers is at right angle and parallel with the grain laid parallel in each layer.
Features:
Excellent dielectric and mechanical properties.
Applications:
It is widely used for production of power transformers.
