Application:

NYM cables intended for transmission and distribution of electric power in fixed installations, as well as for power supply systems requiring compression of cables at insertion are designed for AC voltage 660 V at 50 Hz frequency. Cable is recommended for installation in dry and wet production facilities, industrial and residential buildings, in special cable racks and boxes. Application in the open air is also possible (without direct sunlight). NYM cable is not recommended for in ground installation (in trenches), it can not be used for outdoor installations and for insertion into raw concrete.
