EN 50288-7 Cables
XLPE Insulated, LSZH Sheathed, Overall Screened & Armoured Instrumentation Cables (Single Triple)
RE-2X(St)HSWAH 70°C / 300 V
APPLICATION:
EN 50288-7 cables are used for transmission of analoge and digital signals in instrument and control systems at
chemistry and petr°Chemistry industry plants, power plants, natural gas and petroluem plants, etc... EN 50288-
7 cables are used in the environments which have no corrosive gases are emitted in the event of fire. In case of
fire,EN 50288-7 cables inhibit the propagation of the flames whereby the development of smoke is extremely
low. EN 50288-7 Instrumentation cables are not allowed for direct connection to a low impedance sources, e.g.
public mains electricity supply. With blue sheath it is suitable for intrinsically safe systems.EN 50288-7 cables are
not recommended for direct burial. They are for indoor and outdoor installation, in dry and wet l°Cations; on
racks, trays, in conduits.
