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 on the inner walls of buildings and indoors.
Typical design
Cable structure
1. Conducting vein - a copper soft wire of Ø 0,40; 0.50 or 0.64 mm.
2. Core insulation - polyethylene (PE), continuous.
Insulated cores, sharply different in color, are 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 - synthetic tape (PVC, PET-E, PE or polyamide), applied longitudinally or helically.
6. Screen - aluminum or 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 - polyvinyl chloride plastic compound (PVC).

Execution options
For laying in bundles of cables on cable ducts and in gutters, it is possible to manufacture a TPVng cable with a low-combustibility PVC sheath; upon presentation of requirements for reduced smoke and gas emission - TPVng-LS with a PVC sheath with reduced smoke and gas emission.
