Temporary Grounding Rod for Secondary Networks (LV)

---

ATR04514-1 / ATR04514-2

The temporary grounding rod for secondary networks is used for maintenance services in de-energized low voltage overhead lines.

The electrician can use it to connect phase conductors to the neutral conductor simultaneously, shorting them with a single move.

This rod is constructed with a RITZGLAS® Ø 25 mm tube, aluminum jaws, and rubber storm skirt, delimiting the grip area.

The clamping jaws are connected to the conductor through compression springs, providing faster installation without damaging the conductors.

The aluminum bar used to interconnect the jaws has a screw at its lower end to connect a ground cable

Secondary Networks (LV) Insulated with Multiplex and Conventional Cable with Bare Cable

---

ATR13043-1

| Maximum short-circuit current: 60 cycles - 8 kA

This equipment enables quick, practical and safe installation and innovates the concept of grounding in LV multiplexedcables insulated systems or conventional systems.

Provided with pressure grounding clamps made of aluminum alloy and handles with rubber coating.

Equipped with tail connectors that can be installed on the system at pre-determined locations, using jumper piercing connectors, enabling the quick connection of the equipment to the system.

In order to increase safety of the installation, these tail connectors are provided with special terminals to protect the exposed connection points after the removal of the grounding set.
