Hot stick

In the electric power distribution industry, a hot stick is an insulated pole, usually made of fiberglass. When engaged for live-line working it is used by electric utility workers to protect them from electric shock on energized high-voltage electric power lines. Depending on the tool attached to the end of the hot stick, it is possible to test for voltage, tighten nuts and bolts, and apply tie wires. These tie wires (twisted lengths of ductile wire that fasten the running cable to its supporting insulators), open and close switches, replace fuses, lay insulating sleeves on wires, and perform various other tasks while limiting exposure to electric shock to the crew. By allowing workers to perform tasks from a distance, hot sticks reduce the need for direct contact with energized components, significantly lowing the risk of electrical injuries or fatalities. Their insulating material prevents the flow of electricity through the tool, creating a protective barrier between the worker and the high-voltage source.
