Air Core Self Supported Aerial Telephone Cables
- Used for aerial installation.
- The cable structure is completed by the application of a suitable core wrapping material, copolymer coated moisture barrier, a parallel support messenger that with the core are covered by an overall the 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
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
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 with durable colored tapes and cabled to complete cable core.
Core Wrapping
Anon-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.
Inner Jacket
An extruded black low-density or medium density polyethylene in accordance with ASTM D 1248 encloses the cable core.
Screen
A single flat aluminum tape (0,15 mm thickness of aluminum) coated both side 50 micron polyethylene film applied longitudinally over core covering with an min 5 mm overlap.
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.
