Bried IntroductionElectrical laminated wood is widely used as insulation and supporting material in transformers andinstrument transformers.lt has many merits such as high mechanical strength,high compatibility with transformer oil,etc.And it can be used in 105oC transformer oil for long time.
People usually use this material to make pressure plates,spacer blocks in oil immersed transformers,as wellas 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 ofmaterials 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 hightemperature and high pressure conditions.
Technical data
New wood fiber rigid electrical insulation material Wood fiber rigid electrical insulation material is widely used in transformers, transformers in the insulation, support materials. With the proportion of moderate, high mechanical strength, easy vacuum drying, easy machining advantages, the dielectric constant close to the transformer oil, with a reasonable insulation can be 155 oC long-term use of transformer oil. Electrician laminated wood in the oil-immersed transformer has been widely used in the manufacture of the upper and lower pressure plate, lead bracket, iron yoke pad and other parts used in the transformer to produce clips, it replaced the steel, insulating cardboard, epoxy cardboard, Epoxy glass cloth in these areas, thereby reducing the transformer's weight and material costs. Electrician laminates are made of high-quality beech wood cooking, peeling, drying veneer, coated with a special insulating plastic, the high temperature, high pressure and made.
