Product Description

What is a Shackle Insulator?

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.

Reliable Shackle Insulator Manufacturer

So, where can I buy high quality shackle insulators?
The best way is from a reliable manufacturer in China.
The manufacturer and supplier should have adequate resources and capacity to supply the best shackle insulators for overhead lines.
You should also check to see what other people are saying about the insulators from a particular manufacturer. This is possible by reading shackle insulator reviews.

Why choose L&R?

1. L&R shackle insulator is made from porcelain which is sound thoroughly vitrified.
2. L&R shackle insulators are free from defects and blemishes. The defects will affect the lifetime of the insulator, l&R QC team will inspect 100%.
3. The process of making a stay insulator is by wet treatment on the porcelain. There should be non-porous with high fusion points during the production.
4. L&R shackle insulator surface is smooth and uniform. The surface of the porcelain is free from irregularities and any rough particles.
