GFRP High voltage insulation rod

Product introduction：

The High voltage insulation rod has been engineered base on epoxy polymer resin, strengthened by special type of non alkali non twist glass fiber, produced by using pultrusion technology. The result is a new high performance composite material with excellent prospects in utility industry can be widely used in composite insulator, arrester, reactor and overhead wiring.
