ANSI 52-3 high voltage porcelain disc suspension insulator
ANSI52-3 high voltage porcelain disc suspension insulator is one kind of ball and socket type porcelain suspension insulator. The ball and socket type insulator is named on the basis of the connection way. Except ANSI52-3, ANSI52-5 is also the ball and socket type high voltage porcelain disc suspension insulator.
The composition of the ANSI52-3 high voltage porcelain disc suspension insulator:
The structure of the ANSI 52-3 high voltage porcelain disc suspension insulator:
The ANSI 52-3 high voltage porcelain disc suspension insulator is composed of Insulator shells, metal parts, cotter keys.
ANSI 52-3 disc suspension insulator ANSI 52-3 ceramic suspension insulator
The material of each parts of the ANSI 52-3 high voltage porcelain disc suspension insulator:
Insulator shells: it is made of wet-process porcelain or toughened glass. Shells shall be sound and free from defects that might adversely affects the insulator.
Shell surface: the surface of shells exposed after the assembly, which shall be glazed for porcelain insulator, shall be relatively smooth and free of imperfections.
If the color is gray, it shall be in accordance with ANSIZ55.1.
Metal parts: metal parts, except for cotter keys, shall be made of a good commercial grade of malleable iron, ductile iron, steel, or aluminum. Ferrous parts, other than stainless steel, shall be galvanized in accordance with ASTM A153-82.
Cotter keys: cotter keys shall be made from cold-drawn wire, its material should be bronze, brass, or austenitic stainless steel.
ANSI 52-3 high voltage porcelain disc suspension insulator is just one kind product of China Orient Power, which is an insulator manufacturer. We can offer you the good service, reasonable price and if there are also large amounts of knowledge about insulators in our website.
