General
FRP Rods produced by our company has applied the pultrusion process technology, of which high-quality raw materials of reinforcedglass fibers and epoxy resin are used.
Our FRP Rods are designed and manufactured mainly for compositeinsulator use with a variety of cross section diameters ranging from 6mm to 110mm and any length at option.
Applications
Mainly for power and electrical industries, such as composite/polymerinsulators, insulation rod, thunder arrestor, dry power transformersand resistors, tap changers, switchgears; Cryogenic insulationunderwaterconditions, electrical equipment and so on.
Besides, our pultruded FRP rod could also be used in other variousindustries where insulation, resistance to stress, weathering andcorrosive atmospheres are important.
