After vacuum injection and continuous pultrusion of epoxy glass drawing rods, the glass fibers are impregnated with epoxy resin. It is solidified and used in overhead lines. Commonly used insulators include needle insulators, butterfly insulators, suspended porcelain bottle insulators, porcelain cross arm insulators, rod insulators and tensioning insulators, etc.

Glass insulators have been widely used in power systems due to their excellent electrical performance, anti-corrosion performance, mechanical strength and other characteristics. Next, let's take a detailed look at its advantages.
