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) not subject to permafrost deformations, in conditions of high humidity.
Typical design
Cable structure
1. Conducting vein - a copper soft wire of Ø 0,40 or 0,50 mm.
2. Core insulation - polyethylene (PE), film-porous.
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.
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. The free space between the cores in the core is filled with a hydrophobic aggregate.
6. Belt insulation - a synthetic tape (PET-E, PE, polyamide or paper-polyethylene), applied longitudinally or helically. A layer of hydrophobic aggregate or water blocking tape is laid over the waist insulation.
7. 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.
8. Shell - PE light stabilized.
9. Armor - flat galvanized steel tapes imposed spirally with overlapping. Pillow for armor - PVC tape.
10. Protective hose - PE light stabilized.
