Good Quality porcelain shackle insulator Chinese Supplier

Short Description:

Shackle insulator is suitable for overhead transmission and distribution line terminal, and fixed on tension rod or angle pole to supporting conductors and playing a role in insulating.
As one part of electrical fitting strings, porcelain shackle insulator is used in order to simplify the fitting structure. It is normally used in 400V lines.
It is a type of low voltage insulator usually assembled with upset bolts, secondary racks, or secondary clevises to provide insulation for the conductors on the pole.
The shackle insulator includes a conductor within the groove and it is fixed by using a soft binding wire. They are typically installed horizontally or vertically on low voltage transmission lines.
Most of them are made of porcelain, but some are made of polymer.
