INSULATED AND PVC SHEATHED SIGNAL CABLE
S-YY
according to VDE 0813H1.71
Application
This type
of cable is applied for signalling purposes for
transmission of electrical pilotting impulses
into electrically guided equipments , for
connection of relay groups with external cables ,
as well as for providing of constant connections
between or in signalling equipment racks.

Colour
Coding Cable wires are marked in such a
way that groups of 4,5,6 or 10 different colours
appear according to the following scheme :

Counting
Signal
cable cores are stranded to concentric layers and counted
starting from the outer layer , then all layers toward
cable center. Couinting of all layers is in the same
direction.
