Product Overview
N2XRY Cable is a 0.6/1kV XLPE-insulated steel wire armoured (SWA) PVC-sheathed power cable. VDE naming: N = standard type, 2X = XLPE insulation, R = round steel wires (Runddrahtbewehrung), Y = PVC sheath. Unlike steel tape armour which provides a continuous cylindrical barrier, steel wire armour uses individual galvanized steel wires helically wound around the cable. Wire armour delivers superior tensile strength, better flexural performance, and higher mechanical protection than tape armour — making N2XRY the preferred choice for installations where the cable must withstand longitudinal pulling forces, complex routing through ducts, or heavy mechanical loads such as vertical risers in high-rise buildings.
STA vs SWA: Tape Armour vs Wire Armour
| Property | Steel Tape Armour (STA — N2XBY) | Steel Wire Armour (SWA — N2XRY) |
|---|---|---|
| Armour Type | Double steel tape, helical wrap | Individual steel wires (0.8-3.15mm), helically wound |
| Mechanical Protection | Excellent crush and impact resistance | Superior tensile strength and flexibility |
| Best For | Direct burial, compression loads | Duct pulling, vertical risers, structural stress |
| Tensile Strength | Moderate — tape can tear under longitudinal stress | Very high — each wire is a tensile member |
| Weight | Lighter | Heavier (more steel per metre) |
| Voltage Rating | 0.6/1kV | 0.6/1kV (plus 1.9/3.3kV option per BS 6346) |

Packaging & Delivery
Heavy-Duty Wooden Drum
Iron-reinforced drums required. SWA cables are heavier than STA equivalents — drum strength must match.
Export Wooden Drum
Fumigated solid wood. Standard for international sea freight. Steel-reinforced flanges for 95mm²+.
Custom Packaging
BS 5467/6346 compliant marking, drum labeling, sequential meter marking. MOQ applies.
Typical Applications
Underground Ducts & Pulling
Steel wire armour provides the tensile strength needed for long-distance duct pulling without armour damage.
Heavy Industrial
Factories and processing plants with complex cable routing. SWA handles mechanical stress of industrial environments.
Vertical Risers
High-rise building riser shafts. Wire armour supports the cable's own weight in vertical installations.
Power Stations
Inter-station and auxiliary power connections. XLPE insulation rated 90°C for high ambient temperature areas.
Distribution Networks
LV distribution networks requiring superior mechanical protection per BS 5467 specifications.
Transportation Infrastructure
Railway, metro, and tunnel installations where vibration and structural movement demand wire armour resilience.
