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 0,32; 0.40; 0.50; 0.64 or 0.70 mm.
2. Core insulation - polyethylene (PE), continuous. Insulated cores, sharply different in color, twisted in a pair.
3. Elementary bundle - is formed of 5 or 10 pairs. All pairs in an elementary beam have an individual color. The bundle fastening winding is a synthetic thread or ribbon of individual color for each bundle.
4. The core of the cable consists of elementary 5 or 10 pair bundles (in cables with a number of pairs up to 100 inclusive) or of main bundles (in cables with a number of pairs more than 100). 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 or 0.5 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.
