What armour type is used in the RZ1MZ1-K and why?

For multi-core variants, the cable features a galvanized steel wire armour that provides excellent mechanical protection against impact, crushing, and tensile stress, making it ideal for direct burial and industrial environments. Single-core cables are fitted with aluminium armour instead, which avoids parasitic currents that could overheat the cable and compromise performance. This dual approach ensures optimal electromagnetic compatibility and thermal stability, fully aligning with IEC 60502-1 installation requirements.
