FRP dog bone spacer stick from Hanyao factory is used in a variety of dry transformer applications,it is formed by continuous drawing after high-temperature curing of non-alkaline glass fiber epoxy resin.It is typically used in the middle of the insulation layer of dry-type transformers to provide support and allow air circulation, thereby enabling the transformer to dissipate heat more effectively.
Our FRP dog bones are made from premium materials and manufactured to the highest standards. We use a variety of different materials, including E-glass fiber, polyester resin, and vinyl ester resin. We also employ a variety of different manufacturing processes to ensure our products meet our customers' stringent requirements.
It has comparable strength to steel or concrete braces, but are much lighter and more flexible,which avoid cracking or breaking when it is stressed.They are corrosion-resistant,which enables steady working performance under harsh environments. Moreover,these materials can be recycled and reused, reducing costs and environmental impact.
