ANSI 52-3 disc suspension insulator is made of porcelain ceramic, and is ball and socket type disc suspension porcelain insulator on the basis of the end fittings connection types.
ANSI52-3 disc suspension insulator structure and materials:
ANSI52-3 disc suspension insulator consists of ceramic insulator shells, metal parts and cotter keys. Porcelain disc suspension insulator shells are made of wet-process porcelain. Shells surface is smooth for its glaze and have a better anti-pollution ability.
Metal parts: Cotter keys are made of bronze, brass, or austenitic stainless steel, which called cold-drawn wire, and other metal parts shall be made of a good commercial grade of malleable iron, ductile iron, steel, or aluminum. The hot dip galvanized is according to ASTM A153-82.
