- Product Details
The NA2XSEYBY 3×240 is a three-core medium voltage power cable, designed for heavy-duty underground distribution. Its structural composition includes three stranded aluminum conductors insulated with XLPE, individual copper screens for each core, a protective inner bedding, galvanized steel tape armour (DSTA), and a durable PVC outer sheath. This cable is specifically engineered for primary distribution networks and industrial feeders where high mechanical protection is required. It is suitable for direct burial in the ground, installation in cable trenches, and use indoors or outdoors where the risk of mechanical damage is present.
- The NA2XSEYBY 3×240 is manufactured in strict accordance with DIN VDE 0276-620 and IEC 60502-2.
- Double-layer steel tape armoring provides exceptional protection against crushing and mechanical impact.
- Radial electric field distribution is uniform; Enhanced safety and extended service life.
- The PVC outer sheath is resistant to common soil chemicals, moisture, and UV radiation.
- Halogen-free and flame-retardant options available.

FAQ
What is the main advantage of NA2XSEYBY over N2XSEYBY?
Cost and weight. The "A" stands for Aluminum Conductor, which is significantly lighter and cheaper than the Copper version (N2XSEYBY). It is the preferred solution for long-distance Medium Voltage (MV) distribution where budget optimization is critical.
What is the recommended bending radius for NA2XSEYBY?
Due to the rigid Steel Tape Armor, this cable is stiffer than unarmored versions. The standard minimum bending radius is 15x the overall diameter. Installers must adhere to this to prevent the steel tape from kinking or damaging the internal insulation during laying.
What are the typical voltage ratings for this cable?
NA2XSEYBY is a Medium Voltage (MV) cable. It is most commonly manufactured for 6/10 kV, 12/20 kV, and 18/30 kV systems. It is the standard choice for primary distribution grids connecting power stations to transformers and industrial substations.
