 Colour Codes & Cable Make Up

E) Colour Code & Cable Make Up According to DIN VDE 0815 & 0816

DIN VDE 0815 for Installation Cables

1) VDE 0815 and VDE 0816 Unit Twisted
Colour Code for the following Installation Cable Types:
J-YY . . . Bd, J-HH . . . Bd, J-Y(St)Y . . . Bd,
J-H(St)H . . . Bd and J-2Y(St)Y . . . Bd
Star-quad bundles

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 uncoloured.
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.

2) VDE 0815

Colour Code for the following Installation Cable Types:
J-Y(St)Y . . . Lg
(Pairs in layers)
2-paired installation cables are stranded to a star quad
circuit 1 a-core red, b-core black
circuit 2 a-core white, b-core yellow
4- and multi-paired installation cables
a-core of 1st pair in each layer is red, all other pairs are white.
b-core blue, yellow, green, brown, black in continual repetition.
Counting: from outside to inside.

3) VDE 0815

Colour Code for the following Installation Cable Types:
JE-Y(St)Y . . . Bd, JE-LiYCY . . . Bd, JE-H(St) . . . and JE-HCH . . . Bd
(Industrial Electronic Cables)

Pair-colour-identification
The insulating cores are identified with different basic colours which are repeated in the same sequence in each unit.

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.

DIN VDE 0816 for Outdoor Telephone Cables

Colour Code for the following Outdoor Telephone Cable Types:
A-2Y(L)2Y...Bd and A-2YF(L)2Y...Bd
A-02Y(L)2Y...Bd, A-02YSF(L)2Y..Bd and A-02YF(L)2Y...Bd
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:

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 uncoloured 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.

Design of a sub-unit:
Consist of 5 star quads = 10 pairs (DA)(DA = double core or pair)

Design of a main-unit:
Consist of 5 sub-units = 50 pairs (DA)

Design of a main-unit:
Consist of 10 sub-units = 100 pairs(DA)


Design of a 300-pairs cable:
Consist of 6 main-units, each of 50 pairs (DA)

Design of a 1500 pairs cable:
Consist of 15 main-units, each of 100 pairs (DA)
