What is the primary function of an insulated aerial device?

The primary function of an insulated aerial device is to enable work on energized lines while providing safety and protection for the operators. These devices are specifically designed with insulated materials that prevent electrical current from passing through the equipment to the worker, significantly reducing the risk of electric shock when working near or on live electrical systems. Their construction allows crews to access and perform maintenance tasks on energized conductors without needing to de-energize the lines, which is essential for maintaining power supply and minimizing downtime.

While stability for operators is important, it does not encompass the primary function of the device. Equipment transportation and building repairs, although relevant in some contexts, do not define the main purpose of insulated aerial devices, which is focused on safety during work on energized infrastructure.
