J-YY…2X0.6 Bd

Application

The installation cables are used for telephone and signal transmission for permanent surface or concealed installation in dry and damp rooms, on or under plaster, and on external walls.

Standards

• DIN VDE 0815/DIN 57815

Construction

Telephone Cables

Telephone Cables

Conductors
Solid annealed bare copper sized 0.6mm as per VDE 0295/IEC 60228 Class 1

Insulation
PVC YI1 type to DIN VDE 0207-2

Cabling Element
Star Quads

Cable Core Assembly
Each 4 wires are stranded into a star quad, the quads are stranded to units and the units are stranded to form the core

Core Wrapping
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap prior to sheathing

Screen
Laminated aluminium foil is fully enclosing the core with an overlap

Sheath
PVC YM1 type to DIN VDE 0207 part 5

Ripcord
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal

Drain Wire
Tinned drain wire applied longitudinally to provide continuity of the screen

Colour Code

Quads
The single core is identified by black ring markings:

Side Circuit 1 a-wire without marking
  b-wire 1 mark distance 17mm
Side Circuit 2 a-wire 2 marks distance 34mm
  b-wire 2 marks distance 17mm

 

 

 

Subunits
Basic colours for the wire insulation of the 5 star quads of a basic unit:

Quad 1 Red Quad 2 Green  
Quad 3 Grey Quad 4 Yellow Quad 5 White




The tracer units are coded with a red helix, all other units by a white binder
