Porcelain Shackle Insulator
What is shackle insulator?
Shackle insulator was made by wet process and the material is porcelain or ceramic. so we normally called this type insulator as porcelain shackle insulator or ceramic shackle insulator. Shackle insulators are used in low voltage distribution lines as porcelain strain insulators. And shackle insulator can be used vertically as well as horizontally and it can be directly fixed to a pole with a bolt or to the cross arm. However, the use of such insulators is decreasing after increasing the use of underground cables for distribution purpose.
Porcelain shackle insulator type:
|Wet flashover voltage|
|Dry flashover voltage|
