Air Core PVC Sheathed Telephone Cables
- Used for inside wiring applications and networks.
- The solid conductors are insulated polyvinylchloride compound. Insulated conductors are colored different colors and insulated conductors are stranded quad or pair, which are stranded together into units.
- Than cable core are made by those units.
- Outer jacketing material is PVC in accordance with international standards.
- Outer jacket sequentially marked by hot foil printing method.
- Conductor
Solid annealed electrolytic copper. The conductor sizes are 0.5, or 0.6 mm
Color Coding
Fully color-coding.
Insulation
Two or four insulated wire twisted together. The twist length specially designed to minimize the capacitance unbalance and cross talk.
Cable Core
Stranding of 50 pairs or 100 pairs unit, which is assembled in to 10 pairs groups, assembles the cable core.
Core Wrapping
A Non-hygroscopic dielectric tape is applied helically or longitudinally by a suitable overlap.
Identification
A plastic tape, durable marked by the manufacturer name, year of manufacture, and cable size (if required) is placed under the core wrapping.
Support Messenger
According to ASTM A 475-66T galvanized 7 steel wires stranded rope having minimum 120 kg/mm2 is used as holding rope.
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 is include %2,5 ± 0,5 carbon black for sunrise resistance.
