Cables for indoor residential telecommunication installations - Part 4: Cables up to 1 200 MHz - Grade 4

This European Standard specifies the constructional details and performance requirements for cables for installation in indoor residential cabling systems characterized up to 1 200 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 - 4. del: Kabli za frekvence do 1200 MHz - 4. stopnja

Ta evropski standard določa konstrukcijske podrobnosti in zahteve v zvezi z delovanjem za kable za namestitev v notranje stanovanjske kabelske sisteme za zmogljivosti do 1200 MHz. Kabli v tem evropskem standardu temeljijo na skupnih 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 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 50441-4 (CENELEC) - Cables for indoor residential telecommunication installations - Part 4: Cables up to 1 200 MHz - specifies constructional details and performance requirements for indoor residential telecommunication cables characterized up to 1 200 MHz. The standard targets ICT and BCT applications (telephone, data and TV) as referenced in EN 50173-4 and is intended for cables operating at voltages and currents normally found in communications systems (max 300 V a.c / 450 V d.c; current rating 3 A/mm² unless otherwise specified). Note: the supplied extract corresponds to EN 50441-4:2012.

Key topics and technical requirements

• Cable purpose and scope: Indoor residential telecom cabling for frequencies up to 1 200 MHz to support telephone, computer and TV services.
• Conductor: Solid annealed copper conductors; minimum diameter 0.5 mm (constructions such as copper-clad do not comply).
• Insulation: Polyethylene (EN 50290-2-23) or equivalent materials that maintain compliance; insulation thickness must meet electrical requirements.
• Cable element & core: Pair or quad elements; lay-length per EN 50290-2-1; cores wrapped with non-hygroscopic synthetic tape; screening optional depending on EMC needs.
• Screening: Foil and/or braid options; minimum braid coverage guidance (e.g., 60% for braid alone, 30% when combined with foil) as per EN 50290-2-1.
• Sheath: Thermoplastic compound per EN 50290-2-27 (halogen-free flame retardant) or EN 50290-2-22 (PVC); minimum sheath thickness 0.5 mm; typical sheath colour cream unless specified. Ripcord required under sheath.
• Mechanical, environmental and electrical tests: Defines conductor resistance, dielectric strength, capacitance, attenuation, crosstalk, return loss, unbalance attenuation, fire behaviour (e.g., EN 60332-1-2), and mechanical tests (bending, abrasion, adhesion).
• Identification & labelling: Mandatory sheath marking or identification thread with standard designation, reaction-to-fire class, supplier name and metric/batch/length info.

Applications and who uses it

• Procurement teams and spec writers - to create clear product specifications for residential building telecommunication cabling.
• Cable manufacturers - to design and test indoor telecom cables that meet frequency, mechanical and electrical performance criteria.

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.
