NA2XY vs YJLV – Naming Convention
| Designation | Standard | Region | Meaning |
|---|---|---|---|
| NA2XY | European / IEC | International | N = Standard (VDE) / A = Aluminum conductor / 2X = XLPE insulation / Y = PVC sheath |
| YJLV | Chinese / GB | China | YJ = XLPE insulation / L = Aluminum conductor / V = PVC sheath |
*Both designations refer to the same cable construction: Aluminum conductor, XLPE insulation, PVC sheath, rated 0.6/1kV .*
Why Choose Aluminum (NA2XY/YJLV) Over Copper?
| Feature | Aluminum (NA2XY/YJLV) | Copper |
|---|---|---|
| Weight | ~50% lighter | Heavier |
| Material Cost | 40-60% lower | Higher |
| Conductivity (% IACS) | ~61% | 100% |
| Required size for same ampacity | Approximately 1.5-2 sizes larger | Smaller |
| Corrosion resistance | Good (native oxide layer) | Very good |
| Termination | Requires aluminum-rated lugs | Standard lugs work |
| Flexibility | Good (Class 2 stranded) | Excellent |
Key consideration: When replacing a copper cable with an aluminum cable for the same ampacity, select one to two sizes larger (e.g., 50mm² copper → 70mm² or 95mm² aluminum).
Why Choose XLPE Insulation Over PVC?
| Feature | XLPE (Cross-linked Polyethylene) | PVC (Polyvinyl Chloride) |
|---|---|---|
| Continuous operating temperature | 90°C | 70°C |
| Emergency overload temperature | 130°C | 100°C |
| Short circuit temperature | 250°C | 160°C |
| Current carrying capacity | Higher (due to higher temperature rating) | Lower |
| Dielectric strength | Excellent | Good |
| Moisture resistance | Excellent | Good |
| Environmental impact | Lower (no halogens in insulation) | Higher (contains chlorine) |
Standards Compliance
| Standard | Description |
|---|---|
| IEC 60502-1 | Power cables with extruded insulation for rated voltages 1kV and 3kV |
| IEC 60228 | Conductors of insulated cables |
| GB/T 12706.1 | Chinese national standard equivalent to IEC 60502-1 |
| IEC 60332-1 | Tests on electric cables under fire conditions (flame retardant – optional) |
Installation Guidelines
Preparation
Inspect the cable for any damage to the PVC sheath before installation
Store cables on clean, dry reels, protected from direct sunlight and moisture
Preheat the cable if ambient temperature is below 0°C – cold cable can crack the PVC sheath
Pulling and Bending
| Parameter | Value |
|---|---|
| Minimum bending radius (single core, unarmoured) | 20 × overall diameter |
| Maximum pulling tension | Approximately 15 × conductor cross-section (mm²) in Newtons |
| Sidewall pressure limit | Consult engineering datasheet for specific values |
Termination
Use connectors rated for aluminum – standard copper lugs can cause galvanic corrosion and loose connections
Apply anti-oxidant compound to conductor surfaces before termination
Use torque wrench to ensure proper tightening – aluminum requires more precise torque than copper
Testing After Installation
Perform high voltage test at 3.5kV DC for 15 minutes (per IEC 60502-1)
Check continuity of all conductors
Verify insulation resistance (minimum 100 MΩ)
