NYY Power and Signal Cable
-
The NYY cable definition relates to 0,6/1 kV, PVC insulated and sheathed
(NYY) Power and signal cable 0,6/1 kV, PVC insulated and sheathed Application
The NYY power cable from Zetastone Cable is a distribution and signal power cable for static outdoor application (with protection against direct UV-irradiation), in ground, in water, within facilities, in cable canals, in concrete, in conditions where heavier mechanical loads and specially tensile strains, are not expected. As a widely used IEC60502 cable, it is found in electric power plants, transformer stations, industrial plants, metropolitan networks and in other electric plants, same as for connection of signalling devices in industry, traffic and similar.
