The fiberglass mesh is braided by high strength withoutalkali glass fiber , impregnaing the expoxy resinmixture,then through high temperaturecuring qualitative.It’swidely used in dry type transformer and Reactorwinding,its the good u=insulation material in dry type transformer and reactor winding.The meshsupplied in roll form,dipping uniform and without glue scar and fiber naked.
