52-3 Porcelain Disc Suspension Insulator

Our ANSI 52-3 porcelain disc suspension insulator is engineered for high-
voltage overhead power transmission lines, ensuring reliable insulation and
mechanical support. Designed to meet ANSI C29.2 standards, this porcelain
insulator is ideal for utility infrastructure projects requiring durability and
performance.
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.
