The Shackle & Spool insulators for use on LV cables, these insulators are designed to secure cables to cross arms and buildings.
Porcelain / ceramic spool insulator technical data:
Porcelain spool insulator or ceramic reel insulator definition:
Porcelain spool insulator or ceramic reel insulator is an insulator of generally cylindrical form. Porcelain spool insulator has an axial mounting hole and a circumferential groove or grooves for the attachment of a conductor.
The usage of ceramic reel insulator:
Porcelain spool insulator ANSI 53-1, ANSI 53-2 or reel insulator S.05 are usually used on distribution line and fixed on wooden poles, and ceramic insulator ANSI 53-1, 53-2 and reel insulator S.05 are normally used for low voltage.
