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.
Suspension on the supports.
Typical design
Cable structure
1. Conducting vein - a copper soft wire of Ø 0,40; 0.50; 0.64; 0.70; or 0.90 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. The fastening winding of the bundles and core is a synthetic thread or ribbon of individual color for each bundle.
5. Belt insulation - a synthetic tape (PVC, PET-E or PE), applied longitudinally or spirally. On top of the belt insulation, a water blocking tape can be applied.
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.
The sheath is superimposed simultaneously on the cable and core.
8. Cable - a retinue of steel wires. Cable Ø 3.1 or 3.7 mm.
