Use Of Insulators In Power Lines

high voltage transmission line insulators is primarily used to mechanically fix conductors to a supporting structure and provide electrical isolation between the conductor and the structure. overhead power line insulators, made of ceramic, glass, or composite materials, is designed to maintain high voltage resistance, tensile strength, and environmental weather resistance in power lines, thereby achieving safe electrical isolation between the conductor and the grounding or supporting facilities.

Since tension insulator typically uses metal caps, stranded clamps, or connecting lug bolts at the conductor contact point, its purpose is to reliably support the conductor on an overhead or support structure. However, this structure does not actively cut, peel, or damage the cable insulation layer covering the conductor itself. In other words, the application of dead end insulators does not involve damage or alteration to the conductor insulation layer.
