About

Suspension type polymer insulators mechanically hold the conductor cable and electrically isolate it both from contact from the land and from other conductors. GAMMA polymer suspensions support mechanical loads ranging from 15736lb to 27000 lbs., with resisting tensions between 15kV and 69kV for distribution, and between 115kV and 500kV for transmission.

Polymer insulators are designed and manufactured according to IEC 61109 and ANSI C29.13 standards, to satisfy all applicable requirements, as well as to ensure the quality and performance of the product throughout its length of service.

Polymer dead ends are manufactured with the highest quality raw materials to ensure a perfect assembly between the fiberglass nucleus and HTV silicone. Due to this and to the hydrophobic characteristics of the silicone, humidity cannot enter the nucleus, thus preventing deterioration of the insulator and extending its service life. These products are lightweight, resistant to vandalism, and immune to damage due to ultraviolet rays or solar radiation. These insulators have an aerodynamic design to facilitate self-cleaning by wind and rain.

All polymer suspension end fittings are designed to satisfy their mechanical and electrical functions. We offer different combinations of iron fittings for distribution and transmission lines assemblies: clevis, thimble, ball and socket and Y-clevis type. Depending on the installation site and customer requirements, we also offer iron fittings with a double galvanized layer for use in contaminated environments.
