Product Overview

NA2XBY Cable is a 0.6/1kV XLPE-insulated steel tape armoured PVC-sheathed power cable with aluminium conductor, manufactured to IEC 60502-1. Naming follows VDE convention: N = standard type, A = aluminium conductor, 2X = XLPE insulation, B = steel tape armour (Bewehrung), Y = PVC outer sheath. It is the 90°C XLPE upgrade of NAYBY (70°C PVC) — same Al/STA/PVC construction with XLPE's higher thermal rating (90°C continuous, 250°C short-circuit vs 70°C/160°C for PVC). NA2XBY is the aluminium counterpart of N2XBY (copper conductor), offering significant weight and cost savings for projects where aluminium conductor economics are preferred. Single-core variants use non-magnetic steel tape (aluminium tape) to prevent eddy current heating.

NA2XBY Cable Cross Section with 3D Cutaway and 2D Cross-Section

Outer Sheath — Black PVC, flame retardant
Steel Tape Armour — Double galvanized, helically applied
PVC Bedding — Light blue-grey extruded separation sheath
XLPE Insulation — 90°C, VDE 0276-603 colour coded
Aluminium Conductor — Class 2 stranded per IEC 60228

Aluminium Conductor

Class 1 (solid) or Class 2 (stranded) per IEC 60228. 61% IACS at ~50% weight of equivalent copper. Solid for ≤4mm².

XLPE Insulation

90°C continuous, 250°C short-circuit (max 5s). Test voltage 4kV. VDE 0276-603 colour coded: Brown/Black/Grey/Blue + Green/Yellow.

PVC Bedding

Light blue-grey extruded separation sheath between cores and armour. Protects XLPE from steel tape abrasion during bending.

Steel Tape Armour

Double galvanized steel tape. Non-magnetic (aluminium tape) for single-core to prevent eddy currents. 0.2mm for ≤35mm², 0.5mm for ≥50mm².

PVC Outer Sheath

Black PVC, flame retardant per IEC 60332-1. UV resistant for outdoor installation. Moisture-proof for underground use.

XLPE Over PVC Upgrade

90°C vs 70°C continuous rating. Higher ampacity, better overload and short-circuit tolerance (250°C vs 160°C) compared to NAYBY.

NA2XBY vs NAYBY — when to upgrade: Choose NA2XBY (XLPE 90°C) over NAYBY (PVC 70°C) when the installation requires higher ampacity per cross-section or overload tolerance. The XLPE short-circuit rating (250°C vs 160°C) provides an extra safety margin in industrial networks. Note: NA2XBY multi-core bending radius is 12×D — same as NAYBY, not tighter. For single-core, NA2XBY requires 15×D vs 12×D for NAYBY. For projects with strict budget constraints and standard indoor routing, NAYBY remains cost-effective.

Typical Applications

Underground Distribution

Direct burial in soil for LV power networks. Steel tape armour + XLPE insulation provide the highest reliability for permanent underground installation.

Industrial Feeders

Power supply to high-load motors, transformers, and production lines. 90°C XLPE handles overload conditions that 70°C PVC cannot.

Building Main Supply

Main distribution cables in commercial and residential buildings. 12×D bending radius for multi-core routing through conduits and cable trays.

Solar Farm LV Collection

LV collector circuits in photovoltaic farms. Aluminium conductor economics favour long cable runs; XLPE handles elevated ambient temperatures.

Cable Trays & Trenches

Open-air installation on cable trays or covered trenches. UV-resistant black PVC sheath for outdoor routing between buildings and substations.

Infrastructure Projects

Water treatment, pumping stations, tunnel lighting, and rail infrastructure requiring IEC 60502-1 certified XLPE armoured cable.

NA2XBY vs N2XBY — cost vs performance: NA2XBY uses aluminium conductor with identical XLPE insulation and steel tape armour as N2XBY (copper). Aluminium DC resistance is ~1.68× copper at the same cross-section (IEC 60228). For projects where aluminium conductor economics are acceptable, NA2XBY delivers IEC-certified XLPE performance at substantially lower material cost. Single-core requires non-magnetic (aluminium) tape armour; multi-core uses galvanized steel tape. For maximum conductivity per cross-section, specify N2XBY (copper).
