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.
