Hanyao has firm cooperations with several main factories with good name. Laminated High Densified Perma Wood is used as an insulation material to support others parts in transformers. The raw material beech wood must be carefully selected, it has good durability, high density and good abrasion resistance. Impregnated with special resin and then pressed under high pressure, a durable and chemically resistant product is created. In addition, Hanyao is able to provide customized since the laminated wood can be processed into other kinds of materials as required.
