What Are the Difference Between Clevis Insulator and Glass Insulator?

clevis insulators:
consist of a metal clevis (u-shaped or forked metal piece) with an insulator attached to it.
the insulator part is typically made of porcelain or polymer/composite materials.
designed to mechanically support and secure the conductor (wire/cable) while providing electrical insulation.
the clevis allows the conductor to be attached and suspended from the insulator.
commonly used in overhead power lines and electrical transmission systems.
provide strain relief to withstand mechanical tension and strain on the conductors.

glass insulators:

made entirely of glass material, typically toughened or tempered glass.
do not have a separate metal clevis component.
used primarily for insulation purposes, supporting and separating electrical conductors from surroundings.
come in various designs like pin, suspension, strain, etc.
widely used in electrical and telecommunication systems for lower to medium voltage applications.

in a word, clevis insulators incorporate a metal clevis for mechanical support and use porcelain/polymer insulators, while glass insulators are made entirely of glass material and are primarily used for insulation purposes. so, when selecting glass power line insulators, it is crucial to focus on several key factors as below:

1.electrical properties

2.mechanical strength

3.tensile strength

4.thermal performance

5.thermal stability

6.thermal expansion

7.environmental resistance:

8.weather resistance

9.pollution resistance

10:design and construction:

11.shape and size

12.surface finish

13.service life and maintenance

14.durability
15.ease of maintenance
