Electrical laminated wood is widely used as insulating and supporting material in transformers and instrument transformers. It has many virtues such as moderate specific gravity, high mechanical properties, easy vacuum drying, easy mechanical processing etc. The dielectric constant of this material is close to transformer oil, so it makes a reasonable insulation match. And it can be used in transformer oil of 105°C for long time.
