Application
NAYBY cable is designed for fixed power distribution systems operating at AC 50Hz with a rated voltage of 0.6/1kV. It is ideally suited for:
Industrial power installations
Underground power networks
Cable trenches and tunnels
Outdoor and indoor fixed installations
Thanks to its double galvanized steel tape armor, NAYBY cable offers enhanced mechanical protection against external stress, making it suitable for harsh environments where rigidity and strength are required.
Standards
IEC 60228 – Conductors of insulated cables
IEC 60502-1 – Power cables with extruded insulation for rated voltages up to 1 kV (Um = 1.2 kV)
