1. Central filling made of bundle or copper wire in the center of sector cable core;

2. Round- or sector-shaped, stranded, compacted current-carrying conductor:

- metarial:

АПвВ, АПвБВ, АПвКВ, АПвКаВ, АПвКсВ – aluminum (А),
ПвВ, ПвБВ, ПвКВ, ПвКаВ, ПвКсВ – copper,

- section:

6 kV cables (round-shaped conductor) - 35-240 sq. mm
10, 20, 35 kV cables (round-shaped conductor) – 50–240 sq. mm
6, 10 kV cables (sector-shaped conductor) – 120–240 sq. mm;

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

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

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

6. Separating layer made of semiconducting crepe paper tape;

7. Screen made of copper wires connected by means of copper tape (for sector cables collective screen is applied over three insulated conductors)

- with section of minimum 16 sq. mm for cables with conductor section of 35-120 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 over 300 sq. mm.

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.

8. Interphase filling made of rubber compound;

9. Inner sheath made of PVC compound (for armored cables);

10. Armor made of steel galvanized tapes (Б) or steel galvanized wires (K),
aluminum wires (Ka) or aluminum alloy wires (Kc).

11. Sheath made of PVC compound.
