Electrical laminated wood is widely used in transformers, insulation and support materials
in transformers. It has the advantages of moderate specific gravity, high mechanical
strength, easy vacuum drying, and easy processing. The dielectric constant is close to the
transformer oil, and reasonable insulation can use transformer oil at 105°C for a long
time. Electrical laminated wood has been widely used in oil-immersed transformers to
manufacture upper and lower press plates, lead brackets, iron yoke pads and other
components used for the manufacture of transformer parts. It replaces steel plates,
insulating cardboard, epoxy board, epoxy glass. Cloth and other areas, thereby reducing the
transformer’s weight and material costs. Electrical laminates are made of high-quality
birch wood, peeled, dried and veneered, coated with special insulating glue, and made of
high temperature and high pressure.
