The Shackle Insulator is made from high quality porcelain material since it is one of the best insulators. These are highly reliable for conductors. The Shackle Insulators are designed to meet electricity demands in the most cost effective manner.

In addition, the Porcelain Insulators can endure high amount of temperature and current and are the best solution for maintaining safety in various electrical appliances.

Shackle Insulators are used in low voltage distribution lines. They are also known as spool insulators. Shackle Insulators are used at the end of distribution lines or at sharp turns where there is excessive tensile load on the lines.  These insulators can be mounted either in the vertical or horizontal position. The Shackle Insulator is mounted axially.  The loading is on circumferential grooves in the insulator.  The conductor is secured in the groves by means of soft-bending wires.  The insulators are bolted to the cross-arm of the pole.
