Cable arrangement elements. 

1. Round-shaped, stranded, compacted current-carrying conductor:

- material:

АПвПнг(В)-HF, АПвПнг(А)-HF – aluminum (А),
ПвПнг(В)-HF, ПвПнг(А)-HF – copper.

- section:

6 kV cables - 25-800 sq. mm,
10, 20, 35 kV cables – 35-800 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 tape;

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 150-240 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.

7. Separating layer made of varnished glass tape;

8. Inner sheath made of halogen-free polymer compound;

9. Thermal barrier made of varnished glass tapes;

9. Armor made of steel galvanized wires;

10. Sheath made of halogen-free polymer compound.
