Product Overview
N2XB2Y Cable is a 0.6/1kV XLPE-insulated power cable with double galvanized steel tape armor and HDPE (high-density polyethylene) outer sheath, designed per the VDE designation system. VDE naming: N = standard type, 2X = XLPE insulation, B = steel tape armor (Bewehrung), 2Y = HDPE sheath. The steel tape armor provides robust mechanical protection against crushing, impact, and penetration — making N2XB2Y the cable of choice for direct burial, concrete embedment, and installations exposed to physical hazards, while the HDPE sheath delivers superior moisture and chemical resistance compared to PVC-sheathed alternatives.
Unarmored vs Armored: When to Specify N2XB2Y
| Property | N2XY (Unarmored) | N2XB2Y (Steel Tape Armored) |
|---|---|---|
| Mechanical Protection | None — PVC sheath only | Double galvanized steel tape — crush & impact resistant |
| Direct Burial | Not recommended | Designed for it — primary application |
| Sheath Material | PVC | HDPE — superior moisture/chemical resistance |
| Weight | Lighter | Heavier due to steel tape |
| Bend Radius | 12-15 × D | 12-15 × D (same) |
| Typical Use | Indoor, cable trays, ducts | Direct burial, concrete, water, outdoor exposed |
Cable Construction (8 Layers)
1. Conductor — Copper, Class 1 (solid) or Class 2 (stranded)
2. XLPE Insulation — Cross-linked polyethylene, 90°C rated
3. Filler — Non-hygroscopic PP, ensures circular cross-section
4. Binder Tape — Non-hygroscopic, holds laid-up cores together
5. Inner Sheath — PVC bedding, protects insulation from armor
6. Armor — Double galvanized steel tape, helical wrap
7. Outer Sheath — HDPE (2Y), black, UV and moisture resistant

Packaging & Delivery
N2XB2Y armored cables are heavier than unarmored equivalents — packaging must account for the additional weight and steel tape protection requirements.
Iron-Wooden Drum
Standard for all N2XB2Y shipments. Reinforced composite drums prevent deformation from the cable's weight during transport.
Heavy-Duty Wooden Drum
Fumigated solid hardwood drums for long-distance sea freight. Steel-reinforced flanges available for 185 mm² and above.
Custom Packaging
Customer-specified drum types, cable end caps, desiccant bags for moisture protection, custom marking on drums.
Customization Options
Full OEM/ODM: custom core colors, sheath colors, cable printing, sequential meter marking, steel tape thickness specification. Contact sales for minimum order quantities.
Typical Applications
N2XB2Y is specified wherever mechanical protection from steel tape armor is required, combined with the moisture resistance of an HDPE sheath:
Direct Burial
Underground power distribution in soil, sand, and gravel. Steel tape protects against sharp stones and ground settlement pressure.
Industrial Plants
Heavy industrial environments with risk of impact from vehicles, falling objects, and tool strikes on cable routes.
Power Stations & Substations
Inter-station and inter-building connections where physical protection is required. XLPE insulation handles high ambient temperatures.
In-Water Installation
Suitable for laying in fresh water and wet soil. HDPE sheath provides a lifelong moisture barrier unmatched by PVC.
Concrete Embedment
Cast directly into concrete foundations, floor slabs, and retaining walls. Steel tape withstands concrete pour and vibration stress.
Cable Ducts & Trenches
Underground cable duct systems and open trenches where rodents, soil movement, or construction activity pose a risk to unarmored cables.
