Description
A discharge rod is used to remove residual capacitive charge from a circuit that has been isolated but not yet earthed — the step between switching off and applying portable earths.
This is a telescopic rod: it collapses to a transportable length and extends to the working length for the system voltage, so one rod covers a range of sites rather than a single voltage class. The pole is epoxy fiberglass; the earth connection is a copper cable with a clamp, and the discharge element is available in resistive and non-resistive versions.
Versions are supplied for 10 kV, 35 kV, 50 kV, 110 kV and 220 kV, with rod lengths from 1.1 m to 3 m. Colour and OEM branding are customisable.
Every rod is supplied with its earth cable and is packed as a single item measuring 110 x 15 x 15 cm at 1.5 kg.

Production & Quality
How this discharge rod is produced and checked
Every rod is built on one site: the epoxy fiberglass pole is pultruded on our own line, the telescopic sections are matched by hand, and the assembled rod is insulation tested before it is packed as a single item.
Process — how it is made
- Pole body pultruded on our own line: reinforcement is pulled through a resin bath and a heated die, which sets wall thickness and resin content before the tube is cured.
- Telescopic sections cut to length and squared, then matched so the rod extends to the working length of its voltage class — 1.1 m at 10 kV up to 3 m at 220 kV.
- Resistive discharge element fitted as its own assembly, and the copper earth cable prepared with its clamp at the same station.
- Joints and locking checked section by section, so the rod holds its set length in service instead of creeping back down.
- Color and OEM branding applied last, so a customized run leaves the line finished to the buyer label.
Inspection — how it is checked
- Incoming material check: resin, reinforcement and bought-in metal parts are checked against the specification before they are released to the line.
- Dimensional check on every section — length, tube diameter and squareness of the cut ends.
- In-process checks at the cutting, assembly and earth-cable stations, recorded against the production order.
- Insulation withstand testing before shipment, with third-party testing supported on request.
- Surface check on the finished pole, then a final packing check against the packing list.
