CONSTRUCTION

1. CONDUCTING CORE — copper round core, 1 and 2 class per GOST 22483.
2. INSULATION — from PVC. Insulated cores have a solid coloring according to colours, specified in the bellow table.
3. STRANDING — insulated core of equal cross-section two-, three-, four- and fove-core cables are stranded.
4. WRAPPING — from chalky-rubber thermoplastic elastomer, single-core cables NUM produced without wrapping.
5. SHEATH — from self-extinguishing grey PVC compound. Sheath thickness is shown in the

APPLICATION
For transmission and distribution of power in permanent facilities intended for rated AC voltage of 0.66 kV and 1.0 kV at the frequency of 50 Hz.
For installation in dry and damp production areas, in special cable canals and blocks, in factory and residence buildings. For power supply to electro units which needs to condense cables at input. Cables are not recommended for under ground installation (in trenches).
Cables NUM-O and NUM-J cables do not spread burning at single cabling.
