What is a suspension insulator?

A Disc Suspension Insulator is generally made of disc shape insulator part(such as porcelain part,glass part) and metal accessories.

How does a disc suspension insulator work?

Disc Suspension Insulator is widely used in transmission overhead line,consiting of 1 insulator and a string of insulator, shoulder the important task of hanging wire and insulting the tower.

How many types of suspension insulator?

1.Normal Disc shaped insulator with ball and socket connection or slot conntection.2.Fog Type disc insulator has a long underside of the umbrella to keep the inner part from moist.3.Anti pollution type disc insulator with double shed. which has large creepage distance that can be used in high pollution area.

Factory Acceptance Tests:

1. Measurement of Dimensions
2. Electrical Test
3. Mechanical Failing Load Test

Why choose L&R?1. L&R porcelain insulator is made from porcelain which is sound thoroughly vitrified.2. L&R porcelain 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 porcelain insulator is by wet treatment on the porcelain. There should be non-porous with high fusion points during the production.4. L&R porcelain insulator surface is smooth and uniform. The surface of the porcelain is free from irregularities and any rough particles.
