PrintCable VVG ng 660, 1000 TU 16-705.426-86 and cable VVGng-ND TU U 31.3-2006134-033-2004
Power cables with copper conductive conductors, PVC insulated PVC sheathed low flammability (with low smoke emission during combustion to VVG ng-ND).
Used for the transmission and distribution of electric energy in stationary installations
for rated voltage of 660 V and 1000 V, 50 Hz.
For installation in dry and wet production areas, on special cable racks, in blocks, as well as for installation outdoors.
Cables are flame retardant.
Design
1. Conductor copper, solid or stranded, circular or sector-shaped, class 1 or 2 according to GOST 22483-77.
2. Insulation PVC PVC. Insulated conductors of multi-conductor cables
have distinctive coloring.
3. Stranding insulated conductors of two-, three-, four- and five conductor cables are twisted; wire cables have conductors with same cross section three, four or five cores all conductors with same cross section or one core of a smaller cross section (ground wire or null).
4. Sheath PVC plastic low flammability (with low smoke emission during combustion to VVG ng-ND).
