PPoollyymmeerr IInnssuullaattoorrss All Smart® Polymer Insulators are made with the highest quality hydrophobic silicone rubber. The rubber, metal, and fiber-reinforced
plastic rod are chemically bonded to guarantee total impenetrability, and the end-fitting and FRP joints are completely embedded in
silicone rubber to eliminate imperfections of traditional sealing technology. The core is made of corrosion-resistant fiberglass, and the
end fittings are hot-galvanized steel. All these features result in a top-quality product suitable for even the most demanding
environments. Manufactured in accordance with IEC 61109.
End Fittings In order to obtain the total length of the insulator (L) with different fittings, please refer to the following table:
