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
