EN 50288-7 Cables
APPLICATION
EN 50288-7 armoured LSZH sheathed cables are generally used when the risk of mechanical damage is
increased. The galvanized steel wire armour provides excellent protection. Generally,EN 50288-7 cables are
used within industrial process manufacturing plants for communication, data and voice transmission signals and
services. Also used for theinterconnection of electrical equipment and instruments, EN 50288-7 LSZH sheath can
reduce toxic smoke and fume emission.
