Product Description
Product Description
The laminated wood nuts is made from laminated wood with high density and produced by imported beech veneers. This product is specially used in oil transformers.
To use laminated wood fastener like wood nuts, it can efficiently overcome the shortage of fasteners made from phenolic Bakelite and nylon fasteners. This product has good mechanical strength, good arc resistance, high resistivity and high oil absorption rate, also low dielectric dissipation, after immersed into oil it has certain self-lock property. With improvement of transformer technology, transformers tends to be has high voltage, low dissipation, low partial discharge and higher reliable. More and more transformer manufacturers choose to use wood fasteners for guarantee product quality and reliability.
We can supply compressed laminated nut M6-M20.
