1. Round-shaped stranded compacted current-carrying conductor, corresponds to classes 1 and 2 as per GOST 22483-77: 

- material: 

АПвП, АПвПг, АПвПу, АПвПуг, АПвП2г, АПвПу2г etc. – aluminum (А),
ПвП, ПвПг, ПвПу, ПвПуг, ПвП2г, ПвПу2г etc. – copper, 

- section: 

6, 10, 15 kW cables – 25-1600 sq. mm,
20 kV cables - 35-1600 sq. mm
30 kV cables - 50-1600 sq. mm 

2. Conductor screen made of extruded semiconducting cross-linked polyethylene; 

3. Insulation made of cross-linked polyethylene (Пв); 

4. Insulation screen made of extruded semiconducting cross-linked polyethylene; 

5. Separating layer made of: 

- semiconducting crepe paper tape - for cables without “г” index;
- semiconducting water-blocking tape - for cables with “г” index; 

6. Screen made of copper wires connected by means of copper tape: 

- with section of minimum 16 sq. mm for cables with conductor section of 25-120 sq. mm,
- with section of minimum 25 sq. mm for cables with conductor section of 150-300 sq. mm,
- with section of minimum 35 sq. mm for cables with conductor section of 400 sq. mm and more, 

Note: Screen section is selected depending on short-circuit currents which shall be calculated according to field cable installation conditions. It is possible to manufacture cables with increased screen section.

- two crepe paper tapes or rubber-coated cloth - for cables without “г” index, or polymeric tape,
- two crepe paper tapes or rubber-coated cloth - for cables with “г”, “уг” indices,
- layer of semiconducting water-blocking tape - for cables with “2г”, “у2г“ indices. 

8. Separating layer made of alumopolymer tape (for cables with “2г”, “у2г” indices). 

9. Sheath made of: 

- polyethylene (П) - for cables without “у” index.
- thickened polyethylene (Пу) - for cables with “у” index.
