Air Core Single Sheathed Underground Telephone Cables
- Used for distribution and long distance networks and installed for secondary and primary networks.
- The cable structure is completed by the application of a suitable core wrapping material, copolymer coated moisture barrier and overall the black outer jacketing.
- Outer jacketing material is MDPE, LDPE or HDPE in accordance with ASTM D 1248.
- Outer jacket sequentially marked by hot foil printing method.
- Conductor
Solid annealed electrolytic copper. The conductor sizes are 0.4, 0.5, 0.6, or 0.9 mm
Color Coding
Fully color-coding.
Insulation
Colored foam skin polyethylene insulation and solid insulation in according to ASTM 1248, foam skin insulation with cellular polyethylene covered with skin layer of high density polyethylene compound. Solid insulation made by 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.
Cable Core
Stranding of 50 pairs or 100 pairs unit, which is assembled in to 10 pair groups, assembles the cable core.
Core Wrapping
A non-hydroscopic and dielectric polyester tape is applied helically over the cable core. Applied polyester tape at least overlaps by 5%.
Identification
A plastic tape, durable marked by the manufacturer name, year of manufacture, and cable size (if required) is placed under the core wrapping.
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 an min 5 mm overlap. In customer request 0,15 mm thick aluminum tape could be used.
Outer Jacket
The cable core 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.
