  • Frequently asked questions (FAQ) about cable designation

Whether for a new installation or when expanding cabling in industrial or private applications, clear cable labelling is essential in order to select the cable approved for the respective application and also to ensure effective cable management. Cable types also differ in terms of the temperature, oil or UV resistance of the jacket material.

A certain basic understanding of cable designations is therefore essential in order to directly recognise the technical properties and possible applications of an electrical cable. In addition to the material and design, they can also provide information about the maximum voltage, the temperature range or special protective features such as halogen-free. Particularly in safety-critical areas, the correct selection based on the cable designations plays a key role, as it ensures compliance with legal and technical specifications.

The DIN VDE 0281/0282/0292 standard, which applies throughout Europe, and the DIN VDE 0250 standard, which applies in Germany, provide harmonised labelling to identify cable types beyond doubt. The meaning or specific purpose of a cable is clearly indicated by a type abbreviation and single core cables can be easily distinguished from each other, for example by different colours.

Standardised electric cables usually have a corresponding imprint on the sheath for exact designation. This guide summarises an overview of the different cable types, how the designation of cable types is made up and how the cable designation can be broken down exactly, as well as which cable types are commonly used in electrical engineering.

Cable abbreviations and their meaning at a glance

Cable abbreviations offer a compact and verified way of providing important information about the properties and areas of application of electrical cables. Each abbreviation consists of a combination of letters and numbers that provide information about the structure, materials and special properties of the cable.  

Letters for materials and structure: For example, N stands for a standard cable according to DIN VDE, Y for PVC insulation and M for a cable with a sheath. 

Labelling of protective conductors: A J in the abbreviation indicates a green-yellow protective conductor, while O indicates that the cable is without a protective conductor. 

Additional properties: Additional letters such as Z can stand for halogen-free materials or other special properties required in particular applications. 

Conductor cross-section and number of cores: Numbers complement the abbreviations and indicate the number of conductors and their cross-section in mm² (e.g. 3x1.5 for three conductors with a cross-section of 1.5 mm² each).  

A clear knowledge of these abbreviations enables you to select electrical cables quickly and safely for the respective commercial or private application or to take special environmental conditions into account. Tables for cable designations and electrical cable overviews help to make the meaning of these abbreviations clear at a glance. 

As already mentioned, the cable designation either follows the DIN standard valid throughout Europe, or the cable designation corresponds to the specifications of the nationally applicable VDE standard 0250. The printed, nine-digit type abbreviation means that the identification of wires is not a mystery.


German cable designations / Power cables and wires according to VDE 0250

Maximum rated voltage, type of insulation, with or without protective conductor: The abbreviations printed on a DIN VDE 0250-certified cable provide information at a glance about the purposes for which a cable is suitable. The designation consists of letters and numbers. The letters provide information about the properties and material of the cable. The numbers describe the number and thickness of the cores. A cable type overview thus helps to decipher the designation of electrical cables without any doubt, making the respective cable designation understandable even for laypersons.

NYM cables, which are standardised according to VDE 250, are among the most commonly used wires. NYM cables are often used for surface-mounted, in- or flush-mounted installation. Power cables labelled NYM are also approved throughout the EU for installation in damp or dry rooms in accordance with the DIN VDE 0295 and IEC 60228 cl. 1 or cl. 2 standards. The abbreviation NYM stands for:

  • N = standard cable
  • Y = PVC core insulation
  • M = sheathed cable

Thanks to their standardisation, NYM cables are also inexpensive and available almost everywhere, which further promotes their widespread use.

Common NYM cable types

NYM cable types, such as NYM-J or NYM-O, are often used for fixed installations in buildings and are characterised by their robust PVC insulation and versatility.

The most common cables of this type include NYM-J 3x1.5. Cables that correspond to this cable type are therefore specified as standardised cables, have PVC core insulation and a protective conductor (J). The number combination refers to 3 cores with a cable cross-section of 1.5 mm².

A power cable with the designation NYM-O 5x10 is a 5-core variant without a protective conductor (O). Depending on the manufacturer, the diameter of this NYM cable is approx. 19.2 mm and the cable cross-section is 10 mm².

The cable designation NYY-J indicates that it is an underground cable that can be used in the garden, for example. This is also a standardised cable in which both the sheath and the core insulation are made of PVC (Y). The J indicates that this cable has a green/yellow protective conductor.


Criteria for selecting a NYM cable

When selecting a NYM cable, you should consider several criteria. Firstly, determine the required number of cores and the cross-section of the cable, which can be seen in the designation. For example, a NYM cable with three cores and a cross-section of 1.5 mm² would be suitable for standard installations. The environment in which the cable is to be laid also plays a role. NYM cables are designed for use in dry and damp environments, but offer no protection against direct sunlight or mechanical stress. The colour of the cores is also important to ensure easy assignment and clear differentiation during the installation process. Pay attention to the quality features, such as the material properties of the insulation and sheath, to ensure a long service life and safety of the cables.

Harmonised wires according to VDE 0281/0282

The definition of a harmonised cable states that such a cable is manufactured in accordance with European standards and therefore bears the "H" marking for harmonised. In comparison, non-harmonised wires are recognised according to the respective national standard. Harmonisation primarily serves to standardise the labelling of cables, making it much easier to identify the required wires due to the large number of products available.

The question of the meaning of this type designation often arises in connection with cable labelling. In addition to the maximum rated voltage, the designation of the H07V-K cable, which is one of the flexible wires, provides information about the material used for the core insulation.

The H stands for a harmonised wire, which means that it follows the harmonisation or uniform marking of wires that are used in the low-voltage range and for AC voltages up to 1000 volts. The code number 07 indicates that the electrical cable is designed for a maximum voltage of 450 V between the outer conductor and PE and 750 V between the outer conductors. The V stands for PVC core insulation, the single core cables of this cable type are finely stranded (K) in this case.

As is also usual with NYM cables, the harmonised cable designation provides information about the cross-section of the single core cables. Here, the type designation H07V-K is extended by the cross-section of the core. For example, a cable of type H07V-K 1x1.5 is a cable with a single core cable with a cross-section of 1.5 mm².

Power cables according to VDE 276 Part .... 603, 604, 620, 622

Conductors with cable designations such as NYCY, which are designed for a voltage of 0.6/1 kV, are referred to as power cables. In this case, the cable designation NYCY stands for a VDE-tested underground cable with a concentric conductor. Other common cable designations for power cables include NA2XY. This cable designation for power cables refers to a VDE-tested underground cable that is designed for a voltage of 0.6 - 1 kV or for an increased current carrying capacity.

The designation N2XSY 6/10kV, on the other hand, refers to a 1-core, shielded medium-voltage cable with a PVC sheath, which is designed for a voltage of 6/10 kV and a maximum of 12 kV.

We have summarised details of the most important power cable abbreviations in the following table for cable labelling.

Name Short character meaning
NAYCWY N = standard conductor
A = aluminium conductor
Y = PVC core insulation
CW = concentric copper conductor
Y = PVC sheath insulation
NA2YSEY N = standard conductor
A = aluminium conductor
2Y = insulation or sheath made of thermoplastic polyethylene (PE)
SE = solid sector conductor
Y = PVC sheath insulation
NYY-J N = standard conductor
Y = PVC core insulation
Y = PVC sheath insulation
J = with green-yellow protective conductor
NYCWY N = standard conductor
Y = PVC core insulation
CW = concentric copper conductor
Y = PVC sheath insulation

Fibre optic cables according to VDE 0888

Cable types according to VDE 0888 (in addition to the international standard IEC 60794-1-1) are fibre optic cables (FO), which are primarily used in the communications industry. VDE 0888 also includes cables that combine optical and electrical conductors.

Lichtwellenleiter-nach-VDE-0888

The cable designation for fibre optic cables therefore indicates, among other things, whether it is a pure fibre optic cable or whether the cable also contains electrically conductive cores. As the range of available cable types is extremely wide, the designations of fibre optic cables are much more complex than those of current-conducting NYM cables.
For example, the cable designation U-DQ(ZN)BH 12G 50/125 OM4 U stands for a universal cable (U) with: loose tube (D) that is longitudinally watertight (Q) has a non-metallic strain relief element (ZN) has a metal-free rodent protection (B) has a halogen-free sheath (H) has 12 cores has a gradient fibre/monomode fibre (G) has a core diameter/sheath diameter of 50/125 µm corresponds to performance class OM4 supports 10 Gigabit Ethernet over lengths of up to 400 metres and 100 Gigabit Ethernet over lengths of up to 150 metres
We have summarised the details of the fibre optic cable designation in the following table.

Name Short character meaning
U-DQ(ZN)BH 12G 50/125 OM4 U = universal cable
D = loose tube
Q = longitudinally watertight
(ZN) = non-metallic strain relief element
B = metal-free rodent protection
H = sheath is halogen-free
12 = number of cores
G = gradient fibre
50/125 = core diameter /sheath diameter in µm
OM4 = multimode, 1 Gbit/s up to 1000 metres, 10 Gbit/s up to 550 metres
A-DQ(ZN)B2Y 4G 50/125 OM3 A = outdoor cable
D = loose tube
Q = longitudinally watertight
(ZN) = non-metallic strain relief element
B = metal-free rodent protection
2Y = PE sheath
4 = number of cores
G = gradient fibre
50/125 = core diameter /sheath diameter in µm
OM3 = multimode, 1 Gbit/s up to 550 metres, 10 Gbit/s up to 300 metres
I-V(ZN)H 2E 9/125 OS2 I = inner cable
V = solid core
(ZN) = non-metallic strain relief element
H = sheath is halogen-free
2 = number of cores
E = single-mode fibre
9/125 = core diameter /sheath diameter in µm
OS2 = singlemode, 1 Gbit/s up to 5000 metres, 10 Gbit/s up to 10,000 metres

Conclusion: Cable labelling is the key to safe and efficient electrical installation

Cable labelling is essential for clear and reliable identification of electrical cables. They provide clarity about the intended use and the specific properties of the cables, such as temperature, oil or UV resistance. A good example of this is the NYM cable, which is made of a polyvinyl chloride insulation material and is suitable for use in dry and damp environments. It is robust, offers protection against external influences and is ideal for electrical installations in residential and commercial applications. Harmonised standards such as DIN VDE and their specific type abbreviations standardise the designation of electrical cables and make them easier to understand. This helps to clearly identify the different cable types based on their areas of application and properties. The colour coding and additional labelling also provide information about important parameters such as insulation, protective conductor and sheath material, which simplifies installation and cable management.

Frequently asked questions (FAQ) about cable labelling

How to find the right electrical cable?
Cable designation tables simplify the selection and identification of the correct cable types and ensure reliability in various installation scenarios. 

Which cable designation tables are the most important?
In Germany, there are several tables and standards that explain and standardise cable designations. The most important include DIN VDE 0281/0282/0292: These standards define the labelling and abbreviations for electrical installation cables in Germany. They specify how cables are to be labelled with regard to material, insulation and structure. DIN VDE 0250: This standard specifically describes the labelling and properties of cables for use in buildings and in the industrial sector.

The following questions are frequently asked about cable designations:

What does RE stand for in cable designation?
The cable designation RE stands for a single-wire round cable

What does G stand for in cable designation?
The cable designation G stands for a green/yellow protective conductor

What does N stand for in the cable designation?
The cable designation N stands for standardised cable or VDE type

What does l stand for in the cable designation?
