CONSTRUCTION:
1. Electric conductor – copper single or multiwire, round or sectoral shape, according to 1 or 2 grade, GOST 22483.
2. Insulation from polyvinylchloride compound. Core – insulated conductors twisted between each other and fastened by polypropylene thread (for sectoral conductors). Insulated conductors of multiwire cables have distinct colouring. Neutral conductor insulation has blue colouring. Grounding conductor insulation has two-colouring (green-yellow). Inner сore interval from insulated conductors filled with harness, pressed from polyvinylchloride compound.
3. Inner sheath from polyvinylchloride compound.
4. Shield – copper band, laid above inner sheath
5. Outer sheath from polyvinylchloride compound.
For cable VVGEng(A) inner and outer sheath from low-flammable polyvinylchloride compound.
