Product Description
Suspension type insulators mechanically hold the conductor thus isolating it from contact with land and other conductors. Ziyong suspensions support mechanical and electrical charges ranging from 10,000 to 50,000 lbs. and are available in all tension levels, for both distribution and transmission systems.
Porcelain suspensions are specifically designed to comply with ANSI Class (C29.2-1992) standards, ensuring the performance of both the electrical and mechanical functions, as well as to satisfy all dimensional specifications and applicable requirements.
