Hotsticks (Fiberglass)

Hotsticks (Fiberglass)

An Electrical hot stick is an insulated pole, typically made of fiberglass, used by electric utility workers when engaged on live-line working on energized high-voltage electric power lines, to protect them from possible electric shock. The electrical hot stick is very useful for many different applications. Depending on the tool attached to the end of the hot stick, workers can test for voltage, tighten nuts and bolts, apply tie wires (twisted lengths of ductile wire which 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 not exposing the crew to a large risk of electric shock.

Electrical Hot sticks are made in various lengths, from a few feet long up to telescoping types of 40 feet length. The hot sticks are typically made out of fiberglass that provides electrical insulation. This allows utility workers to perform operations on power lines safely without de-energizing them or while the state of the power line is not yet known. This is essential because certain operations (such as opening or closing combination fuse/switches) must occasionally be performed on an energized line. Additionally, after a fault occurs, the exact state of a line may not be certain; in this case, for reasons of crew safety, the utility workers must treat the line as though it were energized until it can be proven that it is not and safety ground cables can be applied to the line (so that the line is guaranteed to remain grounded/earthed while maintenance is performed upon it). If power tools are fitted to the end of the hot stick, they are usually powered hydraulically rather than electrically because, like the fiberglass of the hot stick, the hydraulic fluid is also a good insulator. The hydraulic power is commonly supplied from the bucket truck (cherry picker or aerial work platform) supporting the workers.

The hot stick not only electrically insulates the worker from the energized conductor, but it also provides physical separation from the source being operated, which reduces the chances of burns that might result from electrical arcing if there is a malfunction of the device being operated.

In the U.S., ASTM Standard F 711 specifies the strict requirements for electrical hot sticks, and U.S. OSHA standards require that hot sticks be inspected and electrically tested every two years.
