Knob Insulator

Knob insulators are a type of electrical insulator used in electrical and electronic equipment components. They are typically made of materials such as porcelain, glass, or plastic, which have high electrical resistance properties.

Knob insulators are designed to provide insulation and support for electrical conductors, such as wires or cables, in various applications. They are commonly used in electrical distribution systems, switchgear, transformers, and other electrical equipment.

The main function of knob insulators is to prevent the flow of electrical current between conductors or between conductors and grounded surfaces. They help to maintain the integrity and safety of electrical circuits by isolating and protecting the conductors from contact with other conductive materials.

Knob insulators are called so because of their shape, which resembles a knob or a cylindrical structure with a threaded hole in the center. This threaded hole allows the insulator to be securely mounted onto a supporting structure, such as a metal or wooden pole, using a threaded rod or bolt.

In addition to their electrical insulation properties, knob insulators also provide mechanical strength and stability to the supported conductors. They can withstand high temperatures, mechanical stress, and environmental factors such as moisture, chemicals, and UV radiation.

Overall, knob insulators play a crucial role in ensuring the safe and efficient operation of electrical and electronic equipment by providing insulation and support to conductors in various applications.
