Specifications:

1, Conductor

Solid annealed copper electrolytic copper. The conductor sizes are 0.4- 0.5- 0.6 or 0.9 mm Anon-hydroscopic and dielectric polyester tape is applied helically over the cable core. Applied polyester tape at least overlaps by 5%.

2, Color Coding

For fully color-coding please refer to annex for detailed information of pair color code and sub unit color codes.

3, Insulation

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

4, Twisting / Quadding

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

5, Cable Core

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.

6, Filling Compound

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

7, Core Wrapping

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

8, Identification

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

9, Flooding Compound / Water blocking Tape

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.

10, 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.

11, Support Messenger

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

12, 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.
