Application

The cables are designed for use as connection between central offices. The cables are suitable for installation in ducts, direct burial in the ground and also for aerial installation with integral suspension strand. Jelly filled option is for subscriber’s cables installed underground or along the edge of pavement. An armoured option is offered for direct burial installations. A figure-8 self support option is offered for aerial installation.

Standards

• VDE 0816

 

 

 

Construction

Conductors
Solid annealed bare copper 0.6 and 0.8mm as per class 1 of VDE 0295/IEC 60228

Insulation
Foam Skin which is a composite polyethylene insulation made of an inner cellular layer and an outer solid skin 2YI1 type as per VDE 0207-2

Twisted Pairs
Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk

Cabling Element
Star Quads

Cable Core Assembly
4 Cores are twisted into star quad. 5 star quads are stranded into a basic unit. 5 or 10 basic units each are stranded into one main unit. The star quads are grouped in units and stranded in layers to form the cable core.Standard make up is per VDE 0816 in the Cable Make Up Diagram

Core Wrapping
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap. These tapes furnish thermal, mechanical as well as high dielectric protection between shielding and individual conductors

Moisture Barrier
A layer of aluminium tape (0.2mm) coated with PE-copolymer on one or both sides is applied longitudinally with overlap over the cable core to provide 100% electrical shielding coverage and ensure a barrier against water vapor

Sheath
Black low density polyethylene type 2YM2 as per VDE 0207-3, being able to withstand exposure to sunlight, temperature variations, ground chemicals and other environmental contaminants Ripcord may be provided for slitting the sheath longitudinally to facilitate its removal

Ripcord
Ripcord may be provided for slitting the sheath longitudinally to facilitate its removal

Spare Pairs (optional)
Spare pairs may be incorporated for 200 and larger pair cables

Continuity Wire (optional)
Tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screen

Optional Construction

Jelly Filled Cable
The cable core interstices are filled with petroleum jelly to avoid longitudinal water penetration withinthe cable. The water resistant filling compound is applied to the air space between non-hygroscopic tape and shield, shield and sheath within the cable core

Armoured Cable
Steel Wire Armour or Corrugated steel tape armour is applied over an optional inner polyethylene sheath. For steel tape version, the 0.15mm thick steel tape is coated with a copolymer and applied with an overlap. An outer polyethylene sheath is applied over the armour
