ANSI 57-24 porcelain line post insulator is ansi standard line post insulator and used in electrical system to prevent unwanted flow of current to the earth from its supporting points, and horizontal line post insulator is the same with its application.
The ANSI 57-24 porcelain line post insulator plays a vital role in electrical system. Electrical Porcelain Insulators are very high resistive path through which practically no current can flow. In transmission and distribution system, the overhead conductors are generally supported by supporting towers or poles. The towers and poles both are properly grounded. So between tower or pole body and current, the ansi standard line post insulator carries conductors to prevent the flow of current from conductor to earth through the grounded supporting towers or poles.
ANSI 57-24 porcelain line post insulator parameters:
Type | 57-24 | ||
Creepage distance | mm | 1016 | |
Dry arcing distance | mm | 368 | |
Cantilever strength | KN | 12.5 | |
Power frequency flashover voltage | Dry | KV | 140 |
Wet | KV | 110 | |
Critical impulse flashover voltage | Positive | KV | 230 |
Negative | 340 | ||
Radio interference voltage | Test voltage to ground | KV | 44 |
Max. RIV at 1 MHz | μV | 200 |
The main cause of failure of overhead line ansi standard line post insulator, is flash over, occurs in between line and earth during abnormal over voltage in the system. During this flash over, the huge heat produced by arcing, maybe cause puncher in insulator body. Viewing this phenomenon the materials used for ANSI 57-24 porcelain line post insulators have some specific properties to avoid it.
ANSI 57-24 porcelain line post insulator and other ansi standard line post insulator products supplied by Orient will meet your requirements.
