EN 50288-7 PE armour Multicore Cables
EN 50288-7 PE armour Multicore cables are generally use for indoor installation and suitable for wet and damp areas. The galvanized steel wire armour provides excellent protection. Generally, the cables are used within industrial process manufacturing plants for communication, data and voice transmission signals and services. Also used for the interconnection of electrical equipment and instruments, the LSZH sheath can reduce toxic smoke and fume emission.
Basic design to EN 50288-7
Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
Insulation: PE compound, EN 50290. 2-23.
Overall Screen: Aluminium/polyester tape with 0.5mm2 screen (7/0.3mm) tinned copper drain wire.
