EN 50288-7 Cables
XLPE Insulated, LSZH Sheathed & Overall Screened, Armoured Instrumentation Cables (Single Pair)
RE-2X(St)HSWAH
APPLICATION
The armoured LSZH sheathed cables are generally used when the risk of mechanical damage is increased. 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 theinterconnection of electrical equipment and instruments, the LSZH sheath can reduce toxic smoke and fume emission.
STANDARDS
Basic design to EN 50288-7
FIRE PERFORMANCE
Note: Asterisk * denotes superseded standard, ** denotes Test temperature +60°C, duration 4h. Retention: min 60% of tensile strength/min.60% of elongation, *** denotes optional.
VOLTAGE RATING
300V
CABLE CONSTRUCTION
