EN 50288-7 Cables 
APPLICATION:
EN 50228-7 cables are used for transmission of analoge and digital signals in instrument and control systems at
chemistry and petrochemistry industry plants, power plants, natural gas and petroluem plants, etc... EN 50228-7
cables are used in the environments which have no corrosive gases are emitted in the event of fire. In case of
fire,EN 50228-7 cables inhibit the propagation of the flames whereby the development of smoke is extremely
low. EN 50228-7 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 50228-7 cables
are not recommended for direct burial. EN 50228-7 cables are for indoor and outdoor installation, in dry and wet
locations; on racks, trays, in conduits.
