ANSI 52-4 disc suspension insulator used on high voltage transmission lines for insulating and supporting conductor lines and is a tongue and clevis type ceramic suspension insulators.
As a professional ceramic suspension insulator manufacturer for high voltage overhead power system in China, Orient Power has got all over the world customers’ recognition in the past over years. ANSI 52-4 disc suspension insulator is designed, produced and tested in accordance with ANSI C29.2 standard C29.1.
ANSI 52-4 disc suspension insulator specifications:
Hot dip galvanized end fittings has a better ability of anti-corrosion.
In order to have a better anti-oxidation ability, Orient Power can manufacturing ANSI 52-4 disc suspension insulator with zinc sleeve as customer’s requirement.
Used on extra high voltage transmission and distribution overhead line as a way of disc suspension insulators string and cannot be taken place by other pin insulator or other porcelain insulators.
Multi-function: Ceramic suspension insulators can be assembled into suspension string and tension string to suspension or support lines.
