Hot sticks are a key tool for work on medium- and high-voltage electrical installations, especially when a safe distance must be maintained.
What are electrical hot sticks?
Electrical hot sticks are elongated insulating rods (such as poles or tubes) made of dielectric materials (such as fiberglass or epoxy resin), which allow the worker to operate or work on energized electrical systems from a distance without risk of electrocution.
What are they used for?
They are used to:
- Open or close disconnect switches.
- Verify the absence of voltage (using detectors).
- Install grounds (with special clamps).
- Handle fuses or energized equipment.
- Clean insulators on live lines.
- Install temporary protective devices.
