A composite insulator is an electrical insulating material made from a combination of dielectric polymers and elastomers. They are used in a variety of applications, including power transmission and distribution, electrical substations, and industrial facilities. When choosing a suspension insulator, there are several factors to consider, such as the environment in which it will be used, the voltage it will be subjected to, and the required mechanical strength. This article will help you choose the right Pin insulator for your application.
