Electrical laminated wood is an insulating and supporting material widely used in transformers and transducers. It has the advantages of moderate specific gravity, high mechanical strength, easy vacuum drying, and easy mechanical processing. Its dielectric constant is close to that of transformer oil, and its insulation coordination is reasonable. It can be used in transformer oil at 105°C for a long time. Electrical laminated wood has been widely used in oil-immersed transformers to make parts such as upper and lower pressure plates, lead brackets, iron yoke pads, etc., and used to make clamps in transformers. It replaces steel plates, insulating paperboards, epoxy paperboards, etc. The application of epoxy glass cloth board in these aspects reduces the weight and material cost of the transformer. Electrical laminated wood board is a veneer made of birch wood by steaming, peeling and drying. After coating with special insulating glue, it is made by high temperature and high pressure.

Features

  1. Electrical insulation:

  Laminate products are very good insulators, so they are widely used in electrical engineering technology.

  2. Flame retardant performance:

  Due to its special composition, it will not burn when the system is on fire, and it has good flame retardancy.

  3. Mechanical strength:

  Under high pressure strength, laminates made of special materials will not shatter.

  4. Heat resistance:

  During the heating process of the laminate, due to its very good stability, it can withstand the high pressure in the range of 120-210°C electronics and 130-210°C mechanical.

  5. Easy to shape:

  When manufacturing laminates, stamping, drilling, machining, shearing and sanding can be done easily.
