ANSI 52-2 disc suspension insulator,high tension disc insulator

ANSI 52-2 disc suspension insulator is also called high tension disc insulator, because the porcelain is main material of it. ANSI 52-2 disc suspension insulator is clevis and tongue type connection way.

ANSI 52-2 disc suspension insulator is used on high voltage overhead T&D transmission and distribution lines, especially for extreme high voltage transmission lines and irreplaceable by other kinds of porcelain insulators. Just like all of electrical insulators, porcelain disc insulators plays a role in supporting and insulation on these overhead lines.

High tension disc insulator includes normal types and anti-pollution types. ANSI 52 series porcelain disc suspension insulator products belong to normal types, and anti-pollution suspension insulator types have a better anti-pollution ability for its special shape with deeper grooves or larger creepage distance.
