A Stay Insulator is a high-strength porcelain or polymer insulating device installed in stay (guy) wires to electrically isolate the lower section of the guy assembly from the energized overhead line. It enhances public safety by preventing hazardous voltages from reaching the ground through the stay wire during conductor faults or insulation failure. Stay insulators are widely used in transmission and distribution networks, telecommunications, and utility pole infrastructure, offering excellent mechanical strength, weather resistance, and long-term electrical insulation performance.
