Collection: Screw Insulator

A Screw Insulator is a type of electrical insulator designed with a threaded shank, allowing it to be easily screwed into wood poles, walls, or other structures.1 Commonly made from porcelain or plastic, these insulators are used to secure and electrically isolate low-voltage conductors, such as fence wires or communication lines, preventing current leakage and ensuring safety.
