Insulator｜Glossary
This section is part of the Coaxial Cable Glossary for RF and coaxial systems.
What Is an Insulator?
An insulator is a material that prevents or significantly reduces the flow of electrical current.
In electrical and RF systems, insulating materials are used to separate conductive components and maintain controlled signal paths.
They play a critical role in ensuring safety, signal integrity, and proper electrical performance.
Insulator in RF and Coaxial Systems
In RF and coaxial systems, an insulator is placed between the inner conductor and the outer conductor.
It maintains a fixed distance between them, which is essential for controlling impedance and ensuring stable signal transmission.
Common insulating materials include foam polyethylene, solid polyethylene, PTFE, and ceramic, each selected based on performance requirements such as frequency range, temperature resistance, and signal loss.
