About

Suspension type insulators mechanically hold the conductor thus isolating it from contact with land and other conductors. GAMMA suspensions support mechanical and electrical charges ranging from 15,000 to 25,000 lbs. and are available in all tension levels, for both distribution and transmission systems.

Porcelain suspensions are specifically designed to comply with ANSI CLASS (C29.2) standards, ensuring the performance of both the electrical and mechanical functions, as well as to satisfy all dimensional specifications and applicable requirements.

The porcelain suspensions portfolio includes FOG type insulators for high-contaminated environments. These are offered in brown or gray glaze according to customer preferences and standards for each country.

Post and cable mount hardware allow insulators to be fixed in suspension and retention designs for a perfect connection. These are manufactured in galvanized steel with different configurations, including double galvanized layer or zinc sleeve - characteristics that satisfy all mounting requirements.
