NA2XSBY single core aluminum power cables wire cord cable Standards
IEC 60502 Part 2
NA2XSBY single core aluminum power cables wire cord cable Application
The single core cables 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 installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.
NA2XSBY single core aluminum power cables wire cord cable Construction
Conductor: Plain aluminium conductor complying with IEC 60228 class 1 or 2.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound firmly bonded to the insulation to exclude all air voids.
Insulation: XLPE
Insulaton Screen: double copper tape or copper wires applied helically with copper tape
Separation Sheath (for armoured cable): The separation sheath comprises a layer of extruded PVC, PE or LSZH, applied under the armour .
Lapped Bedding : The lapped bedding consists of Polyester non woven fabrics .
Armour (for armoured cable): The armour consists of Galvanized steel Tape Armour.
Outer Sheath: PVC, PE or LSZH can be offered as an option.
