It has many merits such as high mechanical strength, high compatibility with transformer oil, etc. And it can be used in 105ºC transformer oil for a long time. People usually use this material to make pressure plates,spacer blocks in oil immersed transformers,as well as clamps in instrument transformers. It can replace steel plate, insulating paper sheets, epoxy paper sheets, epoxy paperboard woven glass fabric lamination in these fields. Thus, the weight of transformer and the cost of materials are reduced. The raw materials of electrical laminated wood is the thin veneer of the birch, stained wood,northeast China ash and other high quality wood. The product is coated with special insulating glue and processed at high temperature and high pressure conditions.Veneer Face Flatness(Unit mm)Normal ThicknessDistance of any point on the uppersurface of the veneer that deviatesfrom the light weight straight rulerVeneer length 500Veneer length 1000≤152.04.0>15…≤251.53.0>25…≤601.02.0>601.01.5Appearance Quality ltemAllowed Range SwellingNot Allowed Cracking Dead Knot Foreign-body Adhering Insect Hole Rot Contamination Bruising ImpressionA few allowed,not effect in usage Color-odds and Splash Patches per sq.m. on surface≤3Please Contact UsMiss: leaMob: 86-18526730323
