Graphite electrode
ø150 x 600 mm graphite electrode.
The fact that graphite exhibits high electrical and thermal conductivity and is unassailable and inert to chemical agents (apart from oxygen at a high temperature), makes it a very suitable element for building an earth electrode.
The reference AT-070H consists of a rigid graphite core surrounded by a layer of graphite powder and salts, which whilst helping to avoid mechanical damage during transportation and installation, also improves the conductivity of the electrode.
In order to optimise its duration and effectiveness, the hole should be filled with a thin clay-like powder and special graphite powder for earthing systems.
