EN 50288-7 Cables


EN 50288-7 armoured LSZH sheathed cables are generally used when the risk of mechanical damage is

increased. Thegalvanized steel wire armour provides excellent protection. Generally,EN 50288-7 cables are used

within industrial processmanufacturing plants for communication, data and voice transmission signals and

services. EN 50288-7 cables used for theinterconnection of electrical equipment and instruments, the LSZH

sheath can reduce toxic smoke and fume emission.
