1. Conducting vein - a copper soft wire of Ø 0,32; 0.40; 0.50; 0.64; 0.70 or 0.90 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 (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 - light stabilized PE.
