Cables AVBbShv at 1 kV, AVBbShng 0.66, AVBbShzng Power cables with aluminum conductors, PVC insulated with a protective cover such as BbShv (low flammability) to the completion of AVBbShv-Power cables with aluminum conductors, PVC insulated protective cover type BbShv AVBbShng-Power cables with aluminum conductors, PVC insulated with a protective cover such as low flammability BbShv. AVBbShzng-Power cables with aluminum conductors, PVC insulation, filling, with protective cover such as low flammability BbShv Construction: 1.Tokoprovodyaschaya lived – aluminum, solid or stranded, circular or sector-shaped, 1 or Class 2 according to GOST 22483. 2.Izolyatsiya – from polivinilxloridnogo plastic (PVC). Insulated conductors mnogozhilnyx cables have distinctive coloring. Isolation nulevyx lived runs blue. Insulation of ground runs dvuxtsvetnoy (green-yellow color).
Thickness isolation is presented in the Appendix. 3. Stranding – insulated conductors of two-,-trex, chetyrex and pyatizhilnyx cables are twisted; dvuxzhilnye cables have conductors with same cross section, trex-, and chetyrex pyatizhilnye have all the veins of the same section or a smaller section of wire (ground wire or zero). Nominal cross nulevyx veins (smaller cross-section) and the ground meet these lived in the Supplement. 4. Belt insulation – in kabelyax with a protective cover such as BbShv vypressovana of PVC plastic in kabelyax brand of PVC plastic AVBbShng low flammability. Poverx skruchennyx lived in kabelyax brands AVBbShzng round and sector conductors superimposed vypressovanaya belt insulation from polivinilxloridnogo plastic low flammability, which should fill in the gaps between isolated conductors 5. Protective cover – such as BbShv: – Armor of two stalnyx tapes, superposed so that the tape overlaps verxnyaya gaps between the turns of the lower belt – a protective hose of PVC plastic vypressovanny in kabelyax AVBbShng grade, PVC compound AVBbShzng of low flammability.
