EN 50288-7 Cables

APPLICATION

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 fire. In case of fire,these cables inhibit the propagation of the flames 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.
