NYBY Cable

Applications Overview

NYBY is a PVC insulated and sheathed cable with galvanised steel tape armour for low voltage power applications. Unlike the XLPE insulated N2XBY cable which has a maximum operating temperature of 90oC, the NYBY cable specifies a maximum of +70oC. Rated 0.6/1kV and manufactured in accordance with IEC 60502-1 and DIN VDE 0276-603, the NYBY cable's PVC outer sheath is flame retardant and commonly used across European power distribution networks. 

The double layer of galvanised steel tape offers the cable a degree of mechanical protection but minimises the additional weight and overall diameter of the cable compared to the armour of flat or round steel wires. As such, the NYBY cable is suitable for static application installations in both internal and external dry and damp environments, including being buried with additional protection. The NYBY cable is available with green/yellow earth conductor in the multicore variants of cores and above, with the option of a reduced size earth in the 3 core cable.

It is the 3 core cable of the NYBY that is most commonly specified and requested, as detailed below, but it is available in larger sizes including of 7 cores and above on request. The NYBY cable is provided with a black outer sheath.

The choice of a PVC insulated and sheathed cable - the NYBY - over an XLPE insulated cable or an LSZH sheathed alternative such as the N2XBH will be dependent on the precise application and installation environment. For each project, the Eland Cables technical team is available for support with specification, including determining the correct NYBY cable, the appropriate current carrying capacity, and the application of any de-rating factors. If you are in doubt as to which cable is the most appropriate for your project, we encourage you to get in touch and discuss it with one of our experts.
