Description:
Fiber glass rod is used for production of silicon rubber insulator of electrical overhead lines. It is an important part of core material of composite insulator. It is pultruded by fiberglass, epoxy resin. The FRP long rod is mainly used for suspension insulator from diameter 8mm to 45mm.
Application:
It is mainly used for composite suspension/tension insulator in overhead transmission line.
Features:
It is used pultrusion process and has good performance of tensile strength.
