Laminated wood is created by cutting rotationally fine birch into veneers, and then gumming, stacking and hot pressing after dried.
It has the advantages of moderate density, high mechanical strength, convenient for vacuum drying, good compatibility with transformer oil, and easy for machining. Also, its dielectric constant is close to that of transformer oil and their insulation coordination is reasonable, so it can be used in transformer oil for a long time.
Electrical laminated wood for oil-immersed transformer, produced by ZTelec Group using birch veneer in the Far East of Russia as raw material which has high density of wood and less knots of panel, possesses the advantages of high product density and excellent dielectric property, and can be used in transformer oil to effectively reduce the dead weight and material cost of transformer.
The mechanical and electrical properties of products are superior to the similar one of other companies.
Its quality is recognized by domestic and foreign large enterprises such as Lens Technology in China and Schneider Electric and sold overseas such as European and American areas.
Can be widely used as insulating and support components in transformer oil, such as coil platen, iron core base plate, trapezoid backing plate, lead mount, clamp and other parts.
