Wires intended use
CYKY-J(O)

Cables are intended for transmission and distribution of electric power in permanent equipment for 450/750 V nominal AC voltage and 50 Hz frequency.

It is recommended to use the given cable type for concealed wiring and individual laying in rectangular cable ducts of appropriate dimensions. Not recommended to be laid in the ground (in trenches)
