15 kv C Neck Distribution Post insulators 4320X-70
About
Line posts are support-type insulators and are installed on wooden, concrete, or metal cross arms. These are specially designed for distribution lines with typical application voltages ranging from 25 kV to 45 kV, as per standard ANSI (C29.7). Their strong and robust structural form provides unequal mechanical and electrical characteristics. Nearly impervious to puncture, these insulators are generally used in areas with hot lighting zones. Designs have a cantilever resistance ranging from 6.6 kN to 12.5 kN.
