This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed for
Use within Certain Voltage Limits (LVD - 2006/95/EC).
1 Scope
This sectional specification relates to EN 50117-1 and should be read in conjunction with this generic
specification. This specification applies to indoor drop cables for use in cabled distribution systems operating
1)
at temperature between -40 °C and +70 °C and at frequencies between 5 MHz and 6 000 MHz and
complying with the requirements of EN 50083. These cables are suitable to implement the network type
Case D as depicted in Figure 1 and subclause 6.6 of EN 60728-1-1:2014.
The purpose of this European Standard is to specify the applicable test methods and requirements for the
electrical, mechanical, and environmental and fire performance of the cables.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 50290-1-2:2004 and
EN 50117-1:2002 apply.
———————
1) This value is valid for applications without ampacity only.
4 Requirements for cable construction
4.1 General
Designing the cable, consideration should be paid 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.
4.2 Inner conductor
The conductor shall meet the requirements of 4.2 of EN 50117-1:2002, and shall be solid and can be plain or
metal coated. Dimensions shall be in accordance with the detailed specification.
There shall be no joint made subsequent to the last drawing operation.
4.3 Dielectric
The dielectric material(s) shall be in accordance with 4.3 of EN 50117-1:2002 and shall consist of polyolefin
materials, with prEN 50290-2-37 (polyethylene) or prEN 50290-2-38 (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,
2)
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 be meet the requirements of 4.4 items
b), f) or g) of EN 50117-1:2002. 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 cable is provided with a metal foil, greater than or
equal to 25 %. These values are also valid for cables with two bi-directional layers of helically wound wires.
Dimensions shall be in accordance with the detail specification.
4.5 Filling compounds
Not applicable.
4.6 Moisture barriers
Not applicable.
4.7 Wrapping layers
Not applicable.
4.8 Sheath
Sheath material(s) shall meet the requirements of the EN 50290-2-22 for PVC or EN 50290-2-27 for halogen
free flame retardant materials.
The sheath shall also meet the requirements of 4.8 of EN 50117-1:2002.
———————
2) Smaller cables are not suitable as the attenuation at 6 GHz might be too high.
Dimensions shall be in accordance with the detail specification.
4.9 Metallic protection
Not applicable.
4.10 Cable integral suspension strand (Messenger wire)
Not applicable.
4.11 Oversheath
Not applicable.
4.12 Fauna proofing
Not applicable.
4.13 Chemical and/or environmental proofing
Not applicable.
4.14 Cable identification
4.14.1 General
Cable identification shall be in accordance with 4.14 of EN 50117-1:2002.
4.14.2 Sheath marking
Sheath marking shall be achieved as a non-degradable print containing the following minimum information:
— designation of the cable;
— attenuation value (in dB/100 m at 800 MHz, rounded);
— screening class;
— Euro-class;
— name of supplier.
EXAMPLE EN 50117-4-2 21 < XXX > Class A < YYY >
4.15 Labelling
Unless otherwise specified in the detail specification drums or coils shall be provided with a label with a non-
degradable print containing the following minimum information:
— designation of the cable;
— attenuation
