Polymer pin insulator is one kind of the Polymer composite insulator, according to different coupling types, pin type insulator can be divided into tie-top pin insulator and clamp-top pin insulator.

Polymer composite insulator inclusions:
Polymer composite insulator consists of FRP core, silicone rubber shed, housing and hardware fittings. Polymer composite insulator is lighter than porcelain insulator, easily to install; and has anti-pollution ability and can be used heavy pollution area. FRP core can be made of hot-dip galvanized steel with high tensile strength. Composite pin insulators have same performance.

Polymer composite insulator function:
Polymer composite insulator r used to support, fixed current-carrying conductor, faces and phase between the conductor and the insulation.
Polymer composite insulator can device between end fittings and overhead lines. Installing on overhead line Polymer composite insulator FRP core can receive the impact of the thunder and lightning, and increase critical impluse flashover voltage.

Polymer pin type insulator is a main type polymer composite insulator, its function as well as other composite insulators. Except this type insulator, Orient Power also manufactures porcelain insulator and glass insulator.
