Multi-element metallic cables used in analogue and digital communication and control - Part 6-1: Sectional specification for unscreened cables characterised up to 250 MHz - Horizontal and building backbone cables

EN 50288-6-1 is a sectional specification for unscreened cables, characterised from 1 MHz up to 250 MHz, to be used in horizontal and building backbone wiring as defined in EN 50173. This sectional specification contains the electrical, mechanical, transmission and environmental performance characteristics of the cables, when tested in accordance with the referenced test methods. This sectional specification is to be read in conjunction with EN 50288-1 which contains the essential provisions for its application. The cables covered in this sectional specification are intended to operate with voltages and currents normally encountered in communication systems. These cables are not intended to be used in conjunction with low impedance sources, for example, the electric power supplies of public utility mains.

L’EN 50288-6-1 est une spécification intermédiaire relative aux câbles non écrantés caractérisés de 1 MHz jusqu'à 250 MHz, destinés à être utilisés dans le câblage horizontal et vertical de bâtiment comme défini dans l’EN 50173. La présente spécification intermédiaire contient les caractéristiques de performances électriques, mécaniques, de transmission et d'environnement des câbles, lorsqu’ils sont soumis aux essais selon les méthodes d'essai référencées. La présente spécification intermédiaire doit être utilisée conjointement avec l’EN 50288-1, qui contient les dispositions essentielles pour son application. Les câbles couverts par la présente spécification intermédiaire sont destinés à fonctionner avec des tensions et des courants rencontrés normalement dans les systèmes de communication. Ces câbles ne sont pas destinés à être utilisés conjointement avec des sources de faible impédance, par exemple, les alimentations électriques du réseau public.

Standard EN 50288-6-1 je področna specifikacija za nezaslonjene kable, ki se lahko uporabljajo za pasovne širine od 1 MHz do 250 MHz v vodoravnem (etažnem) in stavbnem hrbteničnem (medetažnem) ožičenju, kot je določeno v standardu EN 50173. Ta področna specifikacija vsebuje električne, mehanske, prenosne in okoljske karakteristike delovanja kablov pri preskušanju v skladu z navedenimi preskusnimi metodami. Ta področna specifikacija se uporablja skupaj s standardom EN 50288-1, ki vsebuje bistvene določbe za njeno uporabo. Kabli, zajeti v tej področni specifikaciji, so namenjeni za delovanje pri napetostih in tokovih, ki so običajni v komunikacijskih sistemih. Ti kabli niso namenjeni za uporabo z viri z nizko impedanco, na primer z električnim napajanjem javnih omrežij.
