ARRANGEMENT

CONDUCTOR:  aluminum, solid or stranded, round

INSULATION: PVC compound; for cables with "нг(А)" index - fire-resistant PVC compound; for cables with "нг(А)-LS" index - flame-retardant PVC compound with low gas and fume emission. Insulated conductors have distinctive color. Neutral conductor - blue colored; ground conductor - green-and-yellow colored.

STRAND: insulated conductors are stranded. Parallel lay in two-core cables is allowed.

FILLING: for cables with PVC compound insulation - PVC compound. In cables of АВВГз model PVC compound filling shall be laid together with sheath provided that they are easily separated without damage.

SHEATH:  PVC compound; for cables with "нг(А)" index - fire-resistant PVC compound; for cables with "нг(А)-LS" index - flame-retardant PVC compound with low gas and fume emission.

NUMBER OF CONDUCTORS:  1, 2, 3, 4, 5.

CONDUCTOR AREA, mm²:  1.5; 2.5; 4.0; 6.0; 10.0; 16.0; 25.0; 35.0; 50.0.
