Here’s some information about them:
1.Material: They are often made of a fiberglass-reinforced resin rod core, polymer material weathersheds, and metal end fittings.
2.Application: These insulators are intended for use on overhead transmission lines for electric power systems, typically for voltages of 70 kV and above.
3.Types: There are different types of strain insulators such as pin, post, and dead-end insulators. Each type has its specific use cases. For example, pin insulators are preferred for new installations, including bare conductor, tree wire, and covered wire jumpers.
4.Installation: Care should be taken during installation. For instance, polyethylene insulators should not be overtightened as it can damage the neck of the insulator, leading to failure.
