Epoxy Resin Fiber glass rod is adopt glassfiber steeped into epoxy resin pultrusion under high temperature,which have features of light weight,stable mechanical performance,high insulation performance,etc and cover the range of voltage from 10KV to 1000KV.

Tensile performance is particularly outstanding,which tensile strength can up to 1360Mpa or more,we mainly produce:Common rod,

High-temperature rod,Acid-proof rod ect. This product can be used as the core rod of composite insulator, the vaulthing pole of the arresters and the insulant of other high machanical and electrical appliance.

Insulating Solid Rod is made of ECR glass reinforced epoxy resin.We use continuous pultrusion procss .The products fullfill The standard of IEC61109.Insulator core rods also are also called fiberglass rod,FRP rod,GRP rod,fiberglass bar,Insulation rod,fiberglass stick and so on. It is widely used in the electrical industry, our fiberglass epoxy resin rod products be exported to Russia, France, Romania, Hungary, Vietnam and India, and other countries.
