Densified Permawood Description

The electrical insulation perma wood for transformer is made of high-quality birch, which is made by steaming, rotary cutting and drying, coated with special insulating glue, and then made by high temperature and high pressure.

Application

The electrical insulation plywood can be processed to insulating and supportive components such as coil plate, core pad and lead support of transformer or mutual inductor. It can be used in transformer oil for a long time. It is used to make transformers and insulation components in coil transformers, core pads, lead brackets, etc.

Features

The electrical insulation plywood is made of good birch that is rotary cut into thin wood layer and then dried, laminated and hot pressed. It has moderate density and high mechanical strength and it is easy to be dried in vacuum and to be processed. With the dielectric constant close to that of transformer oil, it can be used in transformer oil for a long time.
