XLPE Insulated, LSZH Sheathed Instrumentation Cables
EN50288-7 Cables

 


APPLICATION

EN50228-7 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... EN50228-7

cables are used in the environments which have no corrosive gases are emitted in the event of fire. In case of

fire, EN50228-7 cables inhibit the propagation of the flames whereby the development of smoke is extremely

low. EN50228-7 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. EN50228-7 cables are not

recommended for direct burial. They are for indoorand outdoor installation, in dry and wet l°Cations; on racks,

trays, in conduits.
