EN 50288-7 Instrumentation Cables
XLPE Insulated, lsZH sheathed, CWB screened Instrumentation cables (single Pair)
RE-2X(c)H 90°c / 300V
STANDARDS
Basic design to EN 50288-7
Applications
These 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...
These cables are used in the environments which have no corrosive gases are emitted in the event
of fi re. In case of fi re, these cables inhibit the propagation of the fl ames whereby the development
of smoke is extremely low. 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. These 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.
