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 (details are under study).
4.2 Inner conductor
The conductor shall meet the requirements of Subclause 4.2 of EN 50117-1, and shall be solid or tube.
Individual wires can 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.
4.3 Dielectric
The dielectric material(s) shall be in accordance with Subclause 4.3 of EN 50117-1 and shall consist of
polyolefin materials, with EN 50290-2-23 (polyethylene), EN 50290-2-25 (polypropylene) or any relevant
part of EN 50290-2-XX. 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 2,9 mm, 3,7 mm, 4,8 mm and 7,2 mm.
4.4 Outer conductor or screen
The construction and material of the outer conductor and/or screen shall meet the requirements of
Subclause 4.4, items b), c), f) or g) of EN 50117-1. 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.
