Product DescriptionFlat/round 2 core 1pair telephone
cableApplicationThe cables are designed for using 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. ConstructionConductors Solid annealed bare
copper 0.4/0.6/0.8/1.0mm, as per class 1 of DIN VDE 0295/ BS
6360/IEC 60228 Insulation Cellular polyethylene 2YI2 type as per
VDE 0207-2 Twisted Pairs Insulated conductors are twisted into
pairs with varying lay length to minimize crosstalk 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 Sheath Black low or medium density
polyethylene 2YM2 type as per VDE 0207-3, being able to withstand
exposure to sunlight, temperature variations, ground chemicals and
other environmental contaminants Ripcord Ripcord may be provided
for slitting the sheath longitudinally to facilitate its removal
Spare Pairs (optional) Spare pairs may be provided for large 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 within the 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
Corrugated steel tape armour is applied over an optional inner
polyethylene sheath with an overlap. An outer polyethylene sheath
is applied over the armour Product ParametersType CodeA-Outdoor
