| Model (IEC/VDE) | Conductor Material | Structure (Insulation / Armor / Sheath) | Best Application (Buying Guide) |
|---|---|---|---|
| N2XY | Copper (Cu) | XLPE Insulation / Unarmored / PVC Outer Sheath |
Indoor laying, cable ducts, open air, or industrial power stations without mechanical risk. |
| N2XRY | Copper (Cu) | XLPE Insulation / Round Steel Wire Armored (SWA) / PVC Outer Sheath |
Vertical mine shafts, high drop-off roadways, or applications requiring extreme tensile pulling strength. |
| N2XFY | Copper (Cu) | XLPE Insulation / Flat Steel Wire Armored (SFA) / PVC Outer Sheath |
Underground direct burial where the cable must withstand lateral crushing and external impact pressures. |
| NA2XY | Aluminum (Al) | XLPE Insulation / Unarmored / PVC Outer Sheath |
Cost-effective alternative for main distribution networks, municipal grids, and low mechanical risk channels. |
| NA2XBY1 | Aluminum (Al) | XLPE Insulation / Double Steel Tape Armored (DSTA) / PVC Outer Sheath |
Directly buried underground networks looking for budget-friendly aluminum options with severe anti-crush & rodent protection. |
High Thermal Stability: XLPE insulation allows for a continuous operating temperature of 90°C and short-circuit temperatures up to 250°C.
Superior Durability: PVC outer sheath provides excellent resistance to moisture, chemicals, and UV rays.
Enhanced Protection (NA2XBY1): The double steel tape armor (STA) provides robust defense against mechanical impacts and underground crushing.
Cost-Efficiency (NA2XY/NA2XBY1): Aluminum conductors significantly reduce project costs and cable weight compared to copper.
Direct Burial Ready: Suitable for underground installation in trenches with proper bedding.
Application
Industrial Plants: Power supply and control in factories, refineries, and manufacturing facilities.
Public Infrastructure: Underground power distribution for street lighting, hospitals, and commercial centers.
Energy Sector: Connection in power stations, switchgear, and renewable energy (solar/wind) farms.
Buried Installations: NA2XBY1 is ideal for environments where mechanical damage is a risk (e.g., areas with heavy machinery or rodent activity).

FAQ
1. What is the explicit technical meaning behind N2XY, NA2XY, and NA2XBY1 nomenclatures?
German VDE Coding Alignment:
The alphanumeric designations are strictly standardized under German DIN VDE 0276 and standard IEC 60502-1 frameworks to define distinct material layouts. ‘N’ certifies compliance with national VDE guidelines; ‘A’ dictates an electrical-grade Aluminum conductor (absence of ‘A’ implies premium Copper); ‘2X’ signifies high-dielectric Cross-linked Polyethylene (XLPE) core insulation; ‘B’ specifies Double Steel Tape Armoring (DSTA); and ‘Y’ defines the rugged Polyvinyl Chloride (PVC) outer protective jacket. Matching these letters helps engineering buyers select the precise fit for specialized grid environments.
2. Why specify unarmored N2XY/NA2XY cables over the armored NA2XBY1 variant?
Mechanical Stress & Routing Pathways:
The choice depends entirely on physical external loading and the burial routing profile. Unarmored N2XY and NA2XY cables prioritize lightweight pliability, a smaller bending radius, and effortless raceway pathing, making them the standard choice for indoor cable ducts, open-air cable bridges, and masonry channels free from mechanical risk. Conversely, the heavy NA2XBY1 variant integrates a double steel tape armor (DSTA) layer beneath the jacket, engineered explicitly to withstand lateral soil crushing, rock compression, and subterranean rodent activity during direct underground burial.
3. How do copper and aluminum conductors influence the engineering budgets of low-voltage networks?
Metallurgical Economy vs. Cable Weight:
Opting for the copper core N2XY provides maximum current ampacity, low line impedance, and reduced cross-sectional cable sizing, which cuts down on structural electrical cabinet dimension requirements. Conversely, selecting the aluminum core NA2XY or NA2XBY1 profiles serves as a highly budget-friendly alternative. Lightweight EC-grade aluminum drops total physical cable weight by roughly 40-50%, heavily lowering long-distance ocean shipping freight costs and easing structural load limits on long cable trays.
4. What continuous and short-circuit temperature limits can this VDE series safely withstand?
High-Thermal Integrity & Overload Safety:
Engineered for dependable utility and industrial-grade power loops carrying standard 0.6/1 kV ratings, all three cable families implement premium, super-clean Cross-linked Polyethylene (XLPE) core insulation. This allows the conductors to continuously operate under full load at an elevated continuous temperature of 90°C. In the event of emergency grid overloads or brief short-circuit faults, the molecular matrix safely withstands sudden high thermal spikes up to 250°C for 5 seconds without risking insulation meltdown.
5. What wholesale manufacturing capacities and project logistics support does ZHONGYI CABLE guarantee?
B2B Supply Scale & Regulatory Documentation:
As a dedicated B2B cable manufacturer with 30 years of industrial engineering expertise, we supply N2XY, NA2XY, and NA2XBY1 power cables in single-core and multi-core clusters (spanning 2 to 5 cores and above) with standard cross-sections from 1.5 mm² up to heavy 630 mm² distribution sizes. To protect the dense PVC outer sheath and prevent armor displacement during transit, wholesale orders are wound securely on heavy-duty drums, backed by complete third-party Type Test Reports and Routine Factory Test Certificates.
