Overhead line insulators are used for transmission, distribution lines and electrical traction lines. The design may be different for each application and the product range is wide depending on the dimensional, mechanical and electrical requirements.

Line post composite insulator designs for 12-36kV are all made of glass fibre rod with HTV silicone housing and forged aluminium end fittings. We have a wide selection of types for different applications.
The insulators come with a base pin-, flange- and top fitting for conductor ties, clamps or flange. For this product category, we have developed a special top-clamp with “built-in” wheels for easy stringing of conductors. The clamp adopts most of the standard conductor sizes for distribution lines and is designed for live line working as well.
Composite railway insulators for catenary systems. Cantilever and tension types, all with forged aluminium end fittings specially designed for catenary systems. Other composite line, post insulators on demand. Composite suspension insulators on demand.
Features of Composite Insulator
1.No flaw,crack in the surface and interior ,each bar color uniform(green or light yellow).
2.Can withstand the sawing, milling, planning, drilling, lathe and other mechanical processing.
3.Internal thread can be tapping with screw tap,external thread can be polished,but not allowed to bear overload.
4.It has good damping,creep resistance, fatigue resistance, fracture resistance, high temperature resistance,stress corrosion resistance etc.
