Application
The cable is designed for operation on local primary communications networks and communication lines with a nominal supply voltage up to 145 V AC at a frequency of 50 Hz or a voltage up to 200 V DC.
Placing in the telephone drains, in the collectors, mines, on the walls of the buildings and the suspension on the air lines of communications, in conditions of high humidity.
Typical design
Structure of cables
1. conductive veins - a soft copper wire Ø 0.40; 0.50 or 0.64 mm.
2. Polyethylene (PE) core insulation, film.
Isolated nuclei, with a distinctly different color, are twisted into a pair.
3. elementary package - consists of 5 or 10 pairs. All pairs in an elementary beam have an individual color. Wrap for fastening the beam - kapon wire or tape.
4. The core of the cable consists of 5 or 10 elementary packages (in cables with a number of pairs up to 100 inclusive) or of main packages (in cables with a number of pairs more than 100). The bundle and core fastening wrap is a synthetic thread or ribbon of individual color for each bundle.
5. The free space between the cores in the core is filled with a hydrophobic aggregate.
6. Insulation of the belt - a synthetic tape (PET-E, PE, polyamide or polyethylene paper), applied longitudinally or helically. A layer of hydrophobic aggregate or water blocking tape is placed over the waist insulation.
7. Screen - aluminum-polyethylene strip, applied longitudinally or helically. A mower copper wire Ø 0.4 or 0.5 mm is placed longitudinally below the screen.
8. Shell - PE stabilized slightly.
