Vertical rods

Vertical copper-bonded forged rod with sealing-strengthening bush

The 99.9% pure electrolytic copper bonded onto a drawn steel to a thickness of min 0.250 mm forms molecular and inseparable connection with the steel. The steel core has a high tensile strength of 600 N/mm².
One end of the rod has decreased diameter by hot forging this guarantees the same thickness of the copper layer on the whole length of the rod. The other end has a hole which enables the connection between the rods to increase the length.
The connection of the rods is protected by sealing bush made of stainless steel which provides additional mechanical strength to the connection. The bush levels potential deformations of the feather key that form during the grounding. The rod pin is made by hot forging this hardened the bolt. Therefore there is no need to use the tip. Connection of the rods complies with the requirements of IEC/EN 62561-2 „Lightning protection components (LPSC). Requirements for conductors and earth electrodes”. To drive the forged rod into the ground, the driving stud and tup for mechanical driving or tup for hand driving must be used.

The bush advantage:
– sealing the pin-feather key connection,
– strengthening the mechanical connection,
– eliminating the potential feather key deformations.

Vertical copper-bonded earth rod/grounding rod

They are made of molecularly bonded 99.9% pure electrolytic copper onto a low carbon steel core. The steel core is a bar drawn to the required diameter. The rods are highly resistant to corrosion and because the steel used has a high tensile strength 600 N/mm2, they can be driven by vibrohammers to great depths. The copper jacket is 0.250 mm thick at all points and it ensures a lifetime of more than 30 years.
The threads at the tips of a rod are rolled after copper bonding process, and both steel and copper are rolled into the thread, making it extremely strong. Connection of the rods using threaded coupling complies with the requirements of IEC/EN 62561-2 „Lightning protection components (LPC). Requirements for conductors and earth electrodes”.
