Application
The cable is designed for operation in local primary communication networks and communication lines with a nominal voltage of remote power supply up to 145 V AC at a frequency of 50 Hz or voltage up to 200 V DC.
Laying in soils of all categories (except mechanized - in rocky soils), not subject to permafrost deformations.
Typical design
Cable structure
1. Conducting vein - a copper soft wire of Ø 0,40; 0.50; 0.60 or 0.80 mm.
2. Core insulation - polyethylene (PE), continuous.
Insulated cores, sharply different in color, are twisted into a four. In each four, two veins located diagonally form a working pair.
3. Elementary beam - formed of 5 fours. All fours in an elementary bunch have an individual color.
4. The core of the cable consists of elementary 5 four-way bundles (in cables with the number of fours up to 50 inclusive) or of the main 25 or 50 four-way bundles (in cables with the number of fours over 50). The fastening winding of the bundles and core is a synthetic thread or ribbon of individual color for each bundle.
5. Belt insulation - synthetic tape (PVC, PET-E or PE), applied longitudinally or helically.
6. Screen - aluminum-polyethylene tape, applied longitudinally or helically. A tinned copper wire Ø 0.4 mm is longitudinally laid under the screen.
7. Shell - light stabilized PE.
8. Armor - flat steel galvanized tapes imposed spirally with overlapping. Pillow for armor - PVC tape.
9. Protective hose - PE light stabilized.
Standards / TU

Execution options
It is possible to manufacture a cable with a longitudinal overlay of steel corrugated laminated armor without PVC tapes under the armor.
