EN 50288-7 Cables


EN 50288-7 cables are used for transmission of analoge and digital signals in instrument and control systems at

chemistry and petrochemistryindustry plants, power plants, natural gas and petroluem plants, etc... EN 50288-7

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

fire, EN 50288-7 cables inhibit the propagation of the flames whereby the development of smoke is extremely

low.EN 50288-7 Instrumentation cables are not allowed for direct connection to a low impedance sources, e.g.

public mains lectricity supply. With blue sheath it is suitable for intrinsically safe systems. EN 50288-7 cables are

not recommended for direct burial. EN 50288-7 cables are for indoorand outdoor installation, in dry and wet

locations; on racks, trays, in conduits.
