What is NYAF Cable?
NYAF cable is a fo epytype of Europenoitan-standard (particularly German VDE-standard) flexible multi-strand copper conductor wire with PVC insulation, widely used in industrial control systems, internal equipment wiring, distribution panel connections, and other applications requiring high flexibility.
🔍 Decoding the Designation (German/European Standard)
| Letter | Meaning |
|---|---|
| N | Normenleitung – Standardized cable compliant with German electrical standards (VDE) |
| Y | Insulation material is PVC (Polyvinyl Chloride) |
| A | Conductor is made of bare copper (Kupfer) |
| F | Feindrähtig – Fine-stranded (flexible) conductor, offering excellent bendability |
✅ Therefore: NYAF = Bare copper + fine-stranded flexible conductor + PVC insulation
📏 Key Technical Specifications
| Parameter | Description |
|---|---|
| Conductor Construction | Fine-stranded copper wires (typically IEC 60228 Class 5 or Class 6 – highly flexible) |
| Insulation Material | Polyvinyl Chloride (PVC) |
| Rated Voltage | Usually 300/500 V or 450/750 V (depends on manufacturer and standard version) |
| Operating Temperature | -40°C to +70°C (short-term higher temperatures may be tolerated) |
| Outer Sheath | ❌ No outer sheath – only single-layer insulation |
| Color Options | Available in various colors (red, black, blue, yellow-green, etc.) for phase, neutral, or earth identification |
🏭 Typical Applications
- Internal wiring in industrial control cabinets
- Motor lead wires and transformer connections
- Jumper wires in distribution boards and terminal blocks
- Power cords for mobile equipment (e.g., welding machines, temporary power supplies)
- Flexible wiring in automation systems and robotics
⚠️ Note: Due to the lack of an outer sheath, NYAF cable must not be used directly outdoors, buried underground, or in areas exposed to mechanical damage. For such environments, it should be installed inside protective conduits, cable trays, or replaced with sheathed versions (e.g., NYFAH, NYBY).
🌍 Comparison with Other Common Cables
| Cable Type | Conductor | Flexibility | Outer Sheath | Typical Use |
|---|---|---|---|---|
| NYAF | Fine-stranded copper | ⭐⭐⭐⭐⭐ | No | Internal equipment, control circuits |
| NYM | Solid or stranded (less flexible) | ⭐⭐ | Yes | Fixed building wiring (similar to Chinese BV/BVR in conduit) |
| H07RN-F | Flexible rubber-insulated copper | ⭐⭐⭐⭐ | Yes | Outdoor/mobile use (oil- and weather-resistant) |
| BVR (Chinese standard) | Fine-stranded copper | ⭐⭐⭐⭐ | No | Common flexible wire in China; functionally similar to NYAF |
✅ Summary
NYAF cable is a European-standard, fine-stranded, bare copper conductor with PVC insulation and no outer sheath. Its key features include:
- High flexibility and ease of bending
- Ideal for tight spaces or applications requiring frequent movement
- Single-layer insulation only—not suitable for direct burial or unprotected outdoor use
- Commonly used in industrial machinery, control panels, and motor connections
If you encounter NYAF in a project, it typically indicates compliance with European electrical standards (e.g., VDE, IEC). When used in regions like China, verify whether local certifications (e.g., CCC) are required.
