Product Overview

NA2XRY Cable is a 0.6/1kV XLPE-insulated steel wire armoured PVC-sheathed power cable with aluminium conductor, manufactured to IEC 60502-1 and British Standards BS 5467 / BS 6346. Naming follows VDE convention: N = standard type, A = aluminium conductor, 2X = XLPE insulation, R = round steel wire armour, Y = PVC outer sheath. Unlike NA2XBY which uses double steel tape armour, NA2XRY employs a single layer of galvanized steel wire armour (SWA) providing superior tensile strength and mechanical protection for vertical runs, cable ladder installations, and applications subject to pulling stress. The aluminium conductor offers ~50% weight reduction vs copper N2XRY, making NA2XRY the cost-effective SWA choice for long-distance power distribution, industrial feeders, and infrastructure projects under BS/IEC certification.

Aluminium Conductor

Hard drawn aluminium, stranded circular or shaped per IEC 60228. 61% IACS at ~50% weight of equivalent copper.

XLPE Insulation

90°C continuous, 250°C short-circuit (max 5s). Colour coded per HD 308 S2. Test voltage 4kV.

PVC Bedding

Extruded PVC separation sheath between cores and armour. Protects XLPE insulation from steel wire abrasion.

Steel Wire Armour

Single layer of galvanized steel wires, helically applied. Wire diameters 0.8–3.15mm. Superior tensile strength vs tape armour.

PVC Outer Sheath

Black extruded PVC. Reduced halogen (Cl<15%). Flame retardant per IEC 60332-1. Chemical & oil resistant.

SWA vs STA

Steel wire armour (NA2XRY) provides higher tensile strength and better vertical support than steel tape (NA2XBY). Heavier but mechanically superior.

SWA vs STA — Choosing the Right Armour

Feature	NA2XRY (SWA)	NA2XBY (STA)
Armour Type	Single layer steel wire	Double galvanized steel tape
Tensile Strength	High — suitable for vertical drops	Moderate — horizontal burial only
Bending Radius (multi-core)	20 × D	12 × D
Weight	Heavier (more steel)	Lighter
Typical Use	Cable ladders, vertical risers, pulling stress	Direct burial, cable trays
Primary Standard	BS 5467	IEC 60502-1 / VDE 0276-603

NA2XRY vs N2XRY — aluminium vs copper: NA2XRY uses aluminium conductor (~50% lighter, ~60% cheaper material cost vs copper) with identical XLPE insulation and steel wire armour. Aluminium DC resistance is ~1.68× copper at the same cross-section (IEC 60228). For applications where aluminium conductor economics are acceptable, NA2XRY provides the same BS/IEC certified SWA performance at substantially lower material cost. For maximum conductivity, specify N2XRY (copper).

Delivery Condition	Factory-new, tested per BS 5467 / IEC 60502-1, with test certificate on request

Typical Applications

Underground Distribution

Direct burial in soil where steel wire armour provides superior radial protection and tensile strength for pulled installation.

Cable Ladders & Trays

Ideal for cable ladder systems where SWA's tensile strength supports longer spans between supports without sagging.

Vertical Risers

SWA's high tensile strength makes NA2XRY suitable for vertical cable risers in multi-storey buildings and industrial plants.

Industrial Networks

Power supply to heavy machinery and production lines. BS 5467 certified for demanding industrial environments.

Infrastructure Projects

Water treatment, pumping stations, tunnel lighting, and rail infrastructure requiring BS-standard SWA cable.

Renewable Energy

LV collection in solar and wind farms where long cable pulls benefit from SWA's mechanical strength and aluminium economics.

Reference data notes: Reference site lists short-circuit temperature as 160°C — this is incorrect for XLPE and appears to be a PVC cable value carried over by copy-paste error. The correct XLPE value of 250°C (per IEC 60502-1) is used above. Bending radius values have been clarified: 10×D for unarmoured, 20×D for SWA armoured. No 1-core table was provided on the reference page — single-core SWA is uncommon in BS/IEC practice due to eddy current concerns in AC circuits.
