Colour coded Control Cables JB and SY-JB with green-yellow protective conductor

The combination of colour identification up to 102 cores consists of 11 basic colours. For core-no. 12 and more, one or two additional colour rings or longitudinal stripes are printed on the basic colour. The ring width is approximately 2 mm.

3- to 5-core cables

Colour identification according to VDE 0293 and BS for flexible cables

3 cores = green-yellow/brown/blue

4 cores = green-yellow/black/blue/brown

5 cores = green-yellow/black/blue/brown/black

6- and more core cables

Colour identification as per following table.

The insulation of the conductor gives the first basic colour. The second and the third colour is printed on the basic colour as a form of ring or longitudinal stripe. The cores are to be counted continuously through all layers at the same direction, beginning with inner layer towards outside.

The cores are to be counted continuously through all layers at the same direction, beginning with inner layer towards outside.

This DIN standard regulates the colour coding for the marking of cable cores in communication cables. The tables displayed here for single-core are for colour code without repetition and with repetition from Core 45 onwards. For pair stranding, the colour repetition start from number 45 and above.

For multi-coloured codes, the first colour is for the insulation of the conductor. The 2^nd and 3^rd colours are the ring colours on the core insulator colour. The ring width is 2-3 mm. Less sharpened edges of the identification color are permitted. Cores are counted continuously through all layers in the same direction, from outer layer towards inside

* This type is according to DIN VDE 0100 part 540, table 2 valid only for copper cross-section of 10 mm² and more or Alu 16 mm².

1) Coding in accordance with VDE 0293: 1990-01 / transitional periods until 1 April 2006, beyond that only the coding for 6 or more conductors will continue to exist.

2) Coding in accordance with VDE 0293-308 (valid as of 1 January 2003).

3) Only for certain applications.

The insulating coverings of single cores of a star quad are marked with black rings

The cores of 5 star quads of a sub unit are counted according to the sequence of basic colours:

Quad 1: basic colour of all cores red

Quad 2: basic colour of all cores green

Quad 3: basic colour of all cores grey

Quad 4: basic colour of all cores yellow

Quad 5: basic colour of all cores white

The marker of units are identified with a red helix, the others with white or un-coloured. The quads of sub units are counted according to the sequence of basic colours. The units are counted continuously through all layers beginning in the inner layer.

Pair-colour-identification

The insulating cores are identified with different basic colours which are repeated sequencely in each unit.

Basic colours of pairs

2-paired cables: the cores are stranded to a star quad:

circuit 1: a-core blue b-core red

circuit 2: a-core grey b-core yellow

Each unit is assigned to one group of ring. All cores in each unit are marked with coloured rings and ring-groups. Counting direction in all units is from inside to outside.

The insulating coverings of single conductors of a quad are to be marked with black rings:

The insulating cores of five star quads of a sub-unit must have the following colours:

Quad 1: basic colours of all conductors red

Quad 2: basic colours of all conductors green

Quad 3: basic colours of all conductors grey

Quad 4: basic colours of all conductors yellow

Quad 5: basic colours of all conductors white

The first sub- or main-unit in each layer is to be marked by an open helix of plastic tape of red (marker). All other sub- or main-units must be whipped with an open helix of white or un-coloured plastic tape. The quads of a sub-unit are to be counted according to the sequence of basic colours. In cables with more than 5 star quads, the sub- and main-units must be counted continuously beginning with maker-unit at inner layer towards outside.
