1. Conducting vein - a copper soft wire of Ø 0,40; 0.50; 0.60 or 0.80 mm.

2. Core insulation - polyethylene (PE), continuous.
Insulated cores, sharply different in color, are twisted into a four. In each four, two veins located diagonally form a working pair.

3. Elementary beam - formed of 5 fours. All fours in an elementary bunch have an individual color.

4. The core of the cable consists of elementary 5 four-way bundles (in cables with the number of fours up to 50 inclusive) or of the main 25 or 50 four-way bundles (in cables with the number of fours over 50). 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 mm is longitudinally laid under the screen.

8. Shell - light stabilized PE.

9. Armor - flat galvanized steel tapes imposed spirally with overlapping. Pillow for armor - PVC tape.

10. Protective hose - PE light stabilized.
