Page 1-6
Part 1
2.3 Rated voltage
The rated voltage of a cable is the reference voltage for which the cable is designed, and which serves to
define the electrical tests.
The rated voltage is expressed by the combination of the following values U /U(U ) expressed in kV.
o m
U is the rms. value between any insulated conductor and earth (metal covering of the cable or the
o
surrounding medium); U = 0,6 kV
o
U is the rms. value between any two phase-conductors of a multicore cable or of a system of single-core
cables; U = 1,0 kV
U is the maximum rms. value of the highest system voltage for which the equipment may be used;
m
U = 1,2 kV.
m
In an alternating current system, the rated voltage of a cable shall be at least equal to the nominal voltage of
the system for which it is intended.
If used in d.c. systems, the cables of this HD shall have a maximum voltage against earth not exceeding
1,8 kV.
3 Marking
3.1 Indication of origin
Cables shall be provided with an identification of origin consisting of:
- either the manufacturer's identification thread
- or the continuous marking of the manufacturer's name or trademark, or (if legally protected)
identification number by one of the three following alternative methods:
1) printed tape within the cable,
2) printing in a contrasting colour on the insulation of at least one core,
3) printing, indenting or embossing on the outer surface of the cable.
3.1.1 Continuity of marks
Unless otherwise specified in the particular sections, each specified mark shall be regarded as continuous if
the distance between the end of the mark and the beginning of the next identical mark does not exceed:
- 550 mm if the marking is on the outer surface of the cable,
- 275 mm if the marking is:
1) on the insulation of a sheathed cable,
2) on a tape within a sheathed cable.
NOTE A ‘specified mark’ is any mandatory mark covered by this part of the HD or by the particular requirements of Part 3 onwards of
this HD.
Page 1-7
Part 1
The diagram below shows an example of the marking as used on the outer surface of the cable, where the
word ‘ORIGIN’ is for the mandatory information required by 3.1, and ‘XYZ’ is one of any other mandatory
marks.
3.2 Additional marking
Additional marking requirements may be specified in the particular sections.
3.3 Durability
Printed markings shall be durable. Compliance with this requirement shall be checked by the test specified in
Subclause 2.5.4 of HD 605.
The printed legend shall be legible after carrying out the test.
3.4 Legibility
All markings shall be legible. Printed markings shall be in contrasting colours.
All colours of the identification threads shall be easy to recognise or easily be made recognisable, if
necessary, by cleaning with a suitable solvent.
3.5 Common marking
Under consideration
3.6 Use of the name CENELEC
The name CENELEC, in full or abbreviated, shall not be marked directly on or in the cables.
4 Core identification
The cores shall be identified by colours or numbers, as specified in the particular sections. Colouring shall be
achieved by the use of coloured insulation or by a coloured surface. Each core shall have only one colour
except the core identified by a combination of the colours green and yellow. The colours green and yellow
shall not be used separately as single colours.
If there is more than one black or brown coloured core, one of them may be marked with a white line. The
white line must be at least 0,5 mm wide, but must not cover more than 5 % of the surface of the core.
The colour or numbering schemes relevant to the various types of cables are specified in the particular
sections of this HD.
If the core identification is by colours it shall comply with HD 308 S2, unless otherwise specified in the
particular sections.
When identification is made by numbers, they shall be printed in a colour which contrasts with the core
colour. Marking shall comply with EN 50334 unless otherwise specified.
The colours or numbers shall be clearly identifiable and durable. Durability shall be checked by the test
specified in Subclause 2.5.4 of HD 605.
Page 1-8
Part 1
The distribution of the colours for the core coloured green and yellow shall comply with the following
condition: for every 15 mm length of core, one of these colours shall cover at least 30 % and not more than
70 % of the surface of the core, the other colour covering the remainder.
NOTE The colours green and yellow, when they are combined as specified above are recognised exclusively as a means of
identification of the core intended for use as earth connection or similar protection.
Compliance with these requirements shall be verified by visual examination.
5 General requirements for the construction of cables
Compliance with the requirements specified in 5.1 to 5.8 and in the particular sections of this HD shall be
checked by inspection and by measurements according to the test methods listed in the particular sections.
5.1 Conductors
5.1.1 Material
Conductors shall be either plain or metal-coated annealed copper or plain aluminium or aluminium alloy in
accordance with EN 60228 and with particular requirements in particular sections of this HD.
Conductors shall be either circular or sector in shape, and of solid metal or stranded.
5.1.2 Electrical resistance
The resistance of each conductor at 20 ºC shall be in accordance with the requirements in EN 60228 for the
given class of conductor.
5.1.3 Separator tape
A separator tape may be placed between the conductor and insulation. Unless otherwise specified, it shall
be non-hygroscopic.
It shall be easily removable from the conductor.
5.2 Insulation

and of the type specified in the particular sections.
The test requirements for these compounds are specified in Tables 3 and 4 unless stated otherwise. in the
particular sections.
5.8.2 Application
The oversheath shall be extruded and may consist of one or more layers.
For unarmoured cables the sheath shall not adhere to the cores. A separator, consisting of a film or tape,
may be placed under the oversheath.
5.8.3 Thickness
Unless otherwise specified in the particular sections the following requirements shall apply.
5.8.4 Sheath applied over a smooth surface
For a sheath applied on a smooth cylindrical surface, such as an inner covering, a metal sheath or the
insulation of a single-core, the mean value of the thickness of the oversheath shall be not less than the
specified value for each type and size of cable in the particular sections.
However, the thickness at any place may be less than the specified value provided that the difference does
not exceed 0,1 mm + 15 % of the specified value.
Test methods are specified in Subclause 2.1.2 of HD 605.

5.8.5 Sheath applied over an uneven surface
For a sheath applied on an irregular cylindrical surface, such as a penetrating sheath on an unarmoured
cable without inner covering or a sheath applied directly over armour, metallic screen or concentric
conductor, the smallest thickness at any point, of the oversheath shall not fall below the value specified in
the appropriate particular sections by more than 0,2 mm + 20 % of the specified value.
Test methods are specified in Subclause 2.1.2 of HD 605.
5.8.6 Mechanical properties before and after ageing
The sheath material shall have the characteristics specified in Tables 3 or 4, as appropriate.
5.8.7 Additional properties
These are specified in the particular sections.
6 Tests on completed cables
All cables shall comply with the requirements specified in 5.1 to 5.8 and in the particular sections of this HD
and shall be checked by inspection and by measurements according to the test methods in documents listed
in the particular sections.
7 Sealing and packing
Prior to storage or shipment, cable ends shall be sealed by appropriate measures so that water ingress is
efficiently prevented.
Cables shall be packed as coils or on drums, according to the particular sections.
8 Current ratings
The current intensity that cables to this document can carry is determined by different conditions, either
electrical (voltage drop) or thermal, whichever is most demanding.
The maximum current ratings resulting from thermal limitations are calculated according IEC 60287 or
equivalent existing methods.
These calculations shall take into account the actual installation and operating conditions.
Tabulated current rating values according to the cable type for typical installation conditions may be found in
particular sections.
9 Guide to use and selection of cables
Guidance on the use of cables is given in Annex A.
The particular sections of the HD give supplementary and additional guidance relating to the individual cable
type.
When selecting the cables, attention is drawn to the fact that national conditions or regulations covering for
instance climatic conditions or installation requirements, may exist. These should therefore be followed in
conjunction with the guidance in Annex A and any information in the particular section.
