What is porcelain stay insulator?
 
Porcelain spool insulator also named porcelain reel insulator and also can be called ceramic spool insulator or ceramic reel insulator. This type of insulators is low voltage porcelain insulators and can be used up to 400V distribution line. Normally reel insulators fixed on wooden pole and used to intersection angle for wire. Porcelain spool insulator is also widely used type porcelain insulators. This type insulator looks like porcelain shackle insulators.
