Copper Bonded Steel Earth Rods
Copper Bonded Earth Rods or ground rods are the ideal driven earth electrodes; they offer the installer an economical and efficient earth rod grounding system.
Electrolytic copper is uniformly molecularly bonded onto a high tensile steel core to a pure thickness from 25-250 micron, thus ensuring excellent corrosion resistance and eliminating electrolytic action.
The high tensile steel core ensures strength and hardness allowing the use of power hammers for deep driven systems.
Coupling threads are formed by a rolling process to ensure thread strength and to maintain the integrity of the molecularly bonded copper. The universally used thread rolling technique raises the surface of the rod.

Groundbed Casing
The installation of an open hole deep groundbed with replaceable anode chains allows an economical design up to 300 m depth and requires the presence of a static water level.
The advantages compared to closed hole groundbeds are as follows:
- Trouble-free unlimited life compared to erratic and short (5 years)
life time of closed hole groundbeds. - Possibility of anode replacement, inspection, repair and replacement
of chain components.
The unlimited lifetime of replaceable groundbeds is ensured by stable
non-conductive, corrosion resistant casings.
Casing
The specified casing is selected by considering the external pressure loading which is caused by geological formation, the depth of groundbed, the ratio of borehole diameter to casing diameter and the position of dynamic water level.
Perforated casings are provided with slots which run perpendicular to pipe axis, thus resulting in a minor decrease of collapse resistance as compared with pipes having
longitudinal slots.
The perforated (open) area covers minimum 20 % surface of the casing around anodes.
Installation Equipment / Accessories
- Hoisting devices for lifting and lowering of the pipe string
- Sump pipes for silt deposit
- Centralizers for centralization of casing in the borehole during installation
- Wooden plugs for fastening to the bottom end of casing or sump pipe
- Wooden clamps faced with leather for holding the casing on the ground level
