FRP cross arm
Production process: FRP cross arm is manufactured by high-strength fiberglass as reinforcing material, thermosetting resin as the base, and then taken shape on a special pultruded mold, where the high temperature activates the resin to cure.
Features: light weight and high strength, anti-ageing, aesthetically pleasing appearance, corrosion-resistance, easily maintain, ,insulating capacity, environmental friendliness, UV Resistant Inhibited .
A new material used in urban and rural power grids.
