Conductor: Annealed electrolytic bare copper (Class 2). According to / IEC 60228.
Wiring: conductors arranged in concentric layers. (7-19-37-61) With 2 wiring directions left and right (one per layer).
Earth cables are made of rigid annealed electrolytic copper wires. Class 2 of standard IEC 60228. Wiring of concentric layers.
So, the difference compared to copper cables is the fact that the latter is very flexible. The Earth cable is indeed a rigid cable.
Earth cables are intended for use in a grounding system. Earthing is a mandatory practice both in industrial and domestic installations, as well as in the operation of systems for the production, transmission and distribution of electrical energy.
