Introduction
Electrical insulators are fundamental components in power transmission, electronics, and industrial equipment. But what exactly is an electrical insulator? Simply put, it is a material or device that resists the flow of electric current, preventing energy loss, short circuits, and hazards.
From overhead power lines to household appliances, insulators ensure electricity flows only where it’s intended. In this article, we’ll explain insulator types, functions, and why choosing the right one is vital for your projects.
