Medium Voltage Power Cable
Medium Voltage Power Cable
Applications
The three core cables NA2XSERY are designed for distribution of electrical power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and frequency 50Hz. They are suitable for use for:
● Intdoors and in cable ducts
● Outdoors,underground
● Switch-boards and power stations
● Transformer stations
● Industrial Plants
Due to the good laying and mechanical characteristic, this cable is suitable when mechanical protection is required or in applications where mechanical damages are expected to occur.

Overview AL/XLPE/CWS/PVC/SWA/PVC Cable
NA2XSERY Medium Voltage 3 Cores AL/XLPE/CWS/PVC/SWA/PVC Armoured Power Cable is for power transmission in industrial and construction applications. This cable NA2XSERY offers a design with a aluminium core for superior conductivity and heat dissipation. NA2XSERY features XLPE insulation, PVC jacket, and a SWA armoured construction, providing improved durability and protection against harsh environmental conditions. The three core cables NA2XSERY are designed for distribution of electrical power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and frequency 50Hz. Made with a layer of steel wire armoured (SWA), polyethylene (XLPE) thermosetting insulation, and hard-wearing PVC, these armoured cables can withstand twisting, crushing, impacts, temperature extremes, moisture, chemical hazards, and more. N2XSERY are suitable for use in a range of environments, from industrial installations and manufacturing facilities to construction sites,and other medium-voltage electrical systems.
