4 Requirements for cable construction, design and installation
4.1 General
Cables according to this document are designed for an operating temperature range from −40 °C to
1)
+70 °C and at frequencies between 5 MHz and 1 000 MHz.
When designing the cable, consideration should be given to the maximum admissible current stated in the
detail specification. It is assumed that the raise of temperature of the inner conductor when submitted to the
maximum current under nominal ambient conditions does not affect the mechanical and electrical properties
of the cable.
Cables according to this document may be operated at voltages > 50 V AC or > 75 V DC according to the
detail specification of the manufacturer. However, these cables are not intended for direct connection to the
mains electricity supply or other low impedance sources.
Cables according to this document shall be designed and constructed according to EN 50290-2-1:2005,
Communication cables Part 2-1: Common design rules and construction and according to
EN 50290-4-1:2014, Communication cables - Part 4-1: General considerations for the use of cables -
Environmental conditions and safety aspects Compliance with the essential requirements of the LVD is
2
described in subclause 4.2.2 of EN 50290-4-1 .
The use of cables according to this document including delivery, storage and installation shall be in
accordance with EN 50290-4-2:2014, Communication cables - Part 4-2: General considerations for the use
of cables - Guide to use, unless otherwise specified.
1) This value is valid for applications without ampacity only, see also Table A.1 concerning max. DC current.
2) EN 50290-4-1:2014, 4.2.2 requires the use raw materials according to EN 50290-2-xx series, design
according to EN 50290-2-1 and dielectric tests according to EN 50289-1-3 and to EN 50290-2-1. Voltage
withstanding tests shall be performed between conductors and between the conductors or screen and the
outer surface of the sheath.

When designed and constructed in accordance with EN 50290-2-1:2005 and EN 50117-1:2019 and
submitted to spark testing, (see 5.1.2.5 in Table 1), CATV cables according to this document may be
installed together with Low Voltage cables.
Moreover, the tests according to Clause 5 of this document shall be performed after environmental and
ageing tests. In addition, the raw materials of these cables are defined in the EN 50290 series.
This ensures sufficient stability of the cables related to this characteristic for its life cycle.
Thus these cables are considered safe when:
— they are used for their intended purpose and applications;
— they are used under voltages and currents that do not exceed the limits given in the relevant detail
specification.
All cables covered by this document do not fall under the scope of the RED or the EMC Directive.
Nevertheless, transfer impedance and screening attenuation according to 5.1.3.6 and 5.1.3.7 in Table 2 shall
be specified in the relevant detail specification, if the intended application of the cable is the use in
combination with equipment under the RED or the EMC Directive, see also EN 50290-4-1:2014, 4.2.1.
4.2 Inner conductor
The conductor shall meet the requirements of EN 50117-1:2019, 4.2 and shall be solid and may be plain or
metal coated. Dimensions shall be in accordance with the detail specification.
There shall be no joint made subsequent to the last drawing operation.
In case of metal coated conductor, consideration shall be taken for the compatibility of the connector.
4.3 Dielectric
The dielectric material(s) shall be in accordance with EN 50117-1:2019, 4.3 and shall consist of polyolefin
materials, with EN 50290-2-37:2016 (polyethylene), EN 50290-2-38:2016 (polypropylene). Dimensions shall
be in accordance with the detail specification.
Unless otherwise specified, the nominal diameter over the dielectric should be one of the preferred values,
namely 3,7 mm, 4,8 mm and 7,2 mm.
4.4 Outer conductor or screen
The construction and material of the outer conductor (or screen) shall meet the requirements of
EN 50117-1:2019, 4.4 items b), f) or g). Where option b) is used, a double braid layer is required.
For braid constructions or helically wound wires, the braid angle shall be between 15° and 45°. The coverage
factor shall be greater than or equal to 65 %, or, when the cab
