Porcelain spool insulator ANSI 53-1
Porcelain spool insulator ANSI 53-1 is manufactured from good grade wet process porcelain and used for low voltage overhead line. This type insulator is designed and produced according to ANSI C29.3.
Except the firing surface, all the other surface of porcelain spool insulator ANSI 53-1 should be glazed. And the glaze can be brown, gray or white. The gray or white color porcelain spool insulator ANSI 53-1 are commonly used in United States or some South American countries. If customers required gray color insulator, it should be according to ANSIZ55.1 and conform to munsell notation 5BG 7.0/0.4 with the following tolerances:
1）Hue: ±12(3G to 7B)
2) Value: ±0.5
3) Chroma:-0.2 to +0.6
Maybe for some manufacturers to produce gray or white color porcelain spool insulator ANSI 53-1 are difficult, but for us it is very mature technology and almost have not any flaws. Other gray or white high voltage insulator also has perfect surface.
