Jelly Filled Self Supported
Aerial Telephone Cables
Description
Used for aerial installation. The cable structure is completed by the application of a suitable core wrapping material, flooding
compound, copolymer coated moisture barrier, a parallel support messenger with the core area covered by an overall black outer
jacketing. Outer jacketing material is MDPE, LDPE or HDPE in accordance with ASTM D 1248. These types of cables have excellent
mechanical performance.

Conductor

Identification

Solid annealed electrolytic copper. The
conductor sizes are 0.4- 0.5- 0.6 or 0.9 mm

Color Coding

A plastic tape, durable marked by the
manufacturer name, year of manufacture,
and cable size (if required) is placed under
the core wrapping.

Fully color-coding. Please refer to annex for
detailed information of pair color code and
sub unit color codes.

Flooding Compound /
Water blocking Tape

Insulation
Colored foam skin polyethylene insulation
or solid insulation in according to ASTM
1248, foam skin insulation with cellular
polyethylene covered by skin layer of highdensity polyethylene compound. Solid
insulation is made medium or high-density
polyethylene compound.

Twisting / Quadding
Two or four insulated wire twisted together.
The twist length specially designed to
minimize the capacitance unbalance and
cross talk.

In order to prevent the water resistance,
flooding compound applied over the cable
core. In customer request water blocking
tape could be applied between core wrapping
and aluminum tape in helically or
longitudinally.

Screen
A single flat aluminum tape (0,2 mm
thickness of aluminum) coated both side 50
micron polyethylene film applied
longitudinally over core covering with a min
5 mm overlap. In customer request 0,15 mm
thick aluminum tape could be used.

Cable Core

Support Messenger

Twisted wires are assembled to form
substantially cylindrical groups of ten pairs
(units). Super units are assembled by
suitable number of units which are binded
by durable colored tapes and cabled to
complete cable core.

According to ASTM A 475-66T galvanized
7 steel wires stranded rope having minimum
120 kg/mm2 is used as holding rope.

Filling Compound
The water resistance-filling compound,
which has 85ºC drop point, is applied to the
cable core to provide water resistance.

Core Wrapping
Anon-hydroscopic and dielectric polyester tape
is applied helically over the cable core. Applied
polyester tape at least overlaps by 5%.

Outer Jacket
Over the corrugated steel tape, outer jacket
is extruded black low-density polyethylene
or medium density polyethylene in
accordance with ASTM D 1248. Outer jacket
polyethylene includes %2,5 ±0,5 carbon black
for sunrise resistance. The color of outer
sheath is black.
