How many kinds of porcelain insulator type according to the ANSI standard?
Porcelain insulator production has different standards, according to the ANSI standard; porcelain insulator can be divided into the following types:
According to the ANSI C29.2 production insulator is porcelain suspension insulator, the characteristics of the suspension insulator is more widely applicable voltage grade. When voltage level is too high, suspension insulator can be through the insulator string together.
Porcelain suspension insulator types are: ANSI 52-1，ANSI 52-2， ANSI 52-3， ANSI 52-4， ANSI 52-5， ANSI 52-6， ANSI 52-8， ANSI 52-9A.
According to the ANSI C29.3 production insulator is porcelain spool insulator, the application of spool insulator with similar butterfly insulator. Porcelain spool insulator types are: ANSI 53-1，ANSI 53-2，ANSI 53-3，ANSI 53-4，ANSI 53-5，AS R1, AS R2, AS R8, BS 1617, BS 1617-1.
According to the ANSI C29.4 production insulator is stay insulator, stay insulator applied most is fixed pole. Porcelain stay insulator types are: AS GY1, AS GY2, AS GY3, AS GY4, ANSI 54-1，ANSI 54-2，ANSI 54-3，ANSI 54-4.
According to the ANSI C29.5 and ANSI C29.6 production insulator is pin insulator, Pin insulator is mainly used in power distribution lines. Porcelain pin insulator types are: ANSI 55-1，ANSI 55-2，ANSI 55-3，ANSI 55-4，ANSI 55-5，ANSI 56-1，ANSI 56-2，ANSI 56-3，ANSI 56-4，ANSI 56-5.
According to the ANSI C29.7 production insulator is porcelain line post insulator, line post insulator used in below 132 kv transmission line. Porcelain line post insulator types are: ANSI 57-1，ANSI 57-2，ANSI 57-3，ANSI 57-4，ANSI 57-5，ANSI 57-11，ANSI 57-12，ANSI 57-13，ANSI 57-14，ANSI 57-15，ANSI 57-21，ANSI 57-22，ANSI 57-23，ANSI 57-24，ANSI 57-25.
According to the ANSI C29.9 production insulator is station post insulator, the characteristics of the power station post insulator is part at both ends up and down is the same(electrical fitting or flange), can be connected to other power station post insulator. Porcelain station post insulator types are: ANSI TR205，ANSI TR208，ANSI TR210，ANSI TR214，ANSI TR216，ANSI TR286，ANSI TR308，ANSI TR316 and so on.
