pin ceramic insulator
Pin ceramic insulator, known as distribution porcelain pin type insulator, which is widely used in low cost distribution lines.
Pin ceramic insulator is consisting of an insulating component intended to be mounted rigidly on a supporting structure by means of a pin passing up inside the insulator. The insulating component may consist of one or more pieces of porcelain permanently cemented together. The fixing of the insulating component to the pin can either be separable or permanent (pin insulator with integral pin).
Pin ceramic insulator are classified by standard:
IEC pin ceramic insulator, ANIS pin ceramic standard and BS pin ceramic insulator, AS pin ceramic insulator, GB pin ceramic insulator.
pin ceramic insulator
What is difference ANSI pin ceramic insulator from BS pin ceramic insulator?
Pin ceramic insulator has two types of thread, one is only shaped by porcelain, and this type of insulator will be fitted with lead head spindle. ANSI standard requires like this.
Another thread type is cement a zinc sleeve on the pin inner hole, and this type of insulator will be fitted with steel head spindle. This spindle is according to BS 3288 standard, and has small steel head and large steel head.
In other words, ANSI ceramic standard pin type high voltage insulator distinguishes form BS pin ceramic insulator on the way of the end hardware connection way and material.
