Cables for indoor residential telecommunication installations - Part 2: Screened cables - Grade 2

This European Standard specifies the constructional details and performance requirements for cables for indoor Residential Cabling Systems characterized up to 100 MHz. Cables in this European Standard are based on the common design rules specified in EN 50290-2-1 and are specifically intended for supporting ICT and BCT applications (telephone, computer and TV services) as specified in EN 50173-4. The cables covered in this European Standard 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 electrical power supply of public utility mains. Cables covered in this European Standard may however be subjected to voltages of not more than 300 V a.c. or 450 V d.c and comply with the requirements of the Low Voltage Directive. The maximum current rating per conductor is 3 A/mm? unless otherwise specified in the relevant detail specification.

Kabli za notranjo stanovanjsko telekomunikacijsko montažo - 2. del: Zaslonjeni kabli - 2. stopnja

Ta evropski standard določa konstrukcijske podrobnosti in zahteve v zvezi z delovanjem za kable za notranje stanovanjske kabelske sisteme za zmogljivosti do 100 MHz. Kabli v tem evropskem standardu temeljijo na splošnih pravilih za načrtovanje iz standarda EN 50290-2-1 in so posebej namenjeni za podporo aplikacij ICT in BCT (telefon, računalnik in TV), kot določa EN 50173-4. Kabli, zajeti v tem evropskem standardu, 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. Vendar so kabli, zajeti v tem evropskem standardu, lahko izpostavljeni napetostim do 300 V izmenične napetosti ali 450 V enosmerne napetosti in morajo biti skladni z zahtevami direktive o nizki napetosti. Največji tok na prevodnik je 3 A/mm?, razen če je v ustrezni podrobni specifikaciji navedeno drugače.

Overview

EN 50441-2:2012 - Cables for indoor residential telecommunication installations, Part 2: Screened cables (Grade 1) - specifies construction and performance requirements for screened copper cables used in indoor residential residential cabling systems up to 100 MHz. The standard targets ICT and BCT services (telephone, computer and TV) in accordance with EN 50173-4 and aligns with common design rules in EN 50290‑2‑1. It covers electrical, mechanical and environmental requirements and references relevant test methods and fire-performance standards.
