This high voltage shorting stick is an insulated discharge rod that connects isolated high voltage equipment to earth through a copper hook and an earth lead with clamp, and it is offered in 10kV, 35kV, 110kV and 220kV ratings. Choose the red telescopic rod with resistive and direct discharge ports, or the green straight rod for direct discharge; every model has an epoxy resin pole and a rubber grip.
Features and Benefits
- Telescopic dual purpose rod - the red rod has a resistive discharge port on the pole and a direct discharge port at the hook, so one stick covers both methods
- Epoxy resin insulating pole - keeps your hands well back from the conductor; the 10kV telescopic rod extends to 1 m and closes to 0.65 m for carrying
- Copper hook - 95 mm long and 10 mm thick, it hooks onto the conductor or test object while the charge drains
- Choice of earth lead - standard 5 m black insulated lead with a red clamp, or a 5 m transparent 4 mm² soft copper lead with a toothed black clamp
- Rubber insulated grip - large, moisture resistant handle with a raised collar where it meets the pole
- Straight type option - green jointed rod with a metal hook, 29 mm pole and a 4 m or 5 m lead, for direct discharge only
Applications
- Power system operation and maintenance on isolated high voltage plant
- Meter maintenance work
- Circuit repair after isolation
- Cable repair and discharging test objects after high voltage testing
Note: For trained, authorised personnel only. Disconnect and isolate the supply first, use a rod rated at or above the system voltage, fit the earth lead to a known good earth before the hook touches the conductor, and confirm zero volts with a suitably rated tester before touching any part.

Hook, straight type: Anti oxidation metal hook. Grip: Moisture resistant insulated rubber. Storage: Black fabric carry bag. Q: What is a shorting stick used for? A: A shorting stick connects isolated high voltage equipment to earth so residual charge drains away before work starts. This rod is listed for power system operation, meter maintenance, circuit repair and cable repair.. Q: How do you use a discharge stick safely? A: Isolate the supply, clamp the earth lead to a known good earth, then hold the rubber grip and place the copper hook on the conductor. On the telescopic rod the lead fits either the resistive port or the direct port; confirm zero volts with a rated tester before touching.. Q: What is the difference between the standard and copper lead versions? A: The standard version has a 5 m black insulated lead with a red clamp. The copper lead version has a 5 m transparent 4 mm² soft copper earthing lead of oxygen free copper with a black toothed clamp.. Q: How long is the telescopic discharge rod? A: Extended it is 1 m for 10kV, 1.5 m for 35kV, 2 m for 110kV and 3 m for 220kV. Retracted it measures 0.65 m (10kV and 35kV), 0.81 m (110kV) or 1.15 m (220kV).. Q: What is the straight type discharge rod? A: It is a green jointed epoxy rod with a metal hook for direct discharge only, 29 mm thick, in 1 m (10kV), 1.5 m (35kV), 2 m (110kV) or 3 m (220kV) lengths. It has a 4 m lead on the 10kV and 35kV models and a 5 m lead on the 110kV and 220kV models..
