Aluminum PVC Power Cable / NAYY / VLV Cable Comparison Table
| Model / Term | Standard System Origin | Voltage Rating (U0/U) | Technical Structure Details | Primary Global Market Context |
|---|---|---|---|---|
| NAYY | German VDE Standard (DIN VDE 0276) | 0.6/1 kV | Class 2 stranded aluminum cores, PVC insulation, heavy-duty PVC outer sheath. Exactly identical to VLV. | The most highly recognized commercial code across Europe, North Africa, and CIS countries for buried aluminum grids. |
| VLV | Chinese National Standard (GB/T 12706) | 0.6/1 kV | Class 2 stranded compacted aluminum conductor (Al), PVC insulated, PVC outer jacket. | Standard nomenclature utilized in mainland China and for sourcing exact replacements on China-built infrastructure. |
| Aluminum Cu/PVC/PVC | International Standard (IEC 60502-1) | 0.6/1 kV | Descriptive material term based on standard IEC engineering nomenclature guidelines. | Universally accepted across Southeast Asia, Middle East, and worldwide bid tender specifications. |
| NA2XY | Premium VDE Variant (DIN VDE 0276) | 0.6/1 kV | Class 2 stranded aluminum, upgraded **XLPE insulation**, PVC jacket (China standard YJLV equivalent). | Higher-tier thermal alternative often specified alongside NAYY for heavy industrial networks requiring 90°C resilience. |
Highly Cost-Effective: Aluminum conductors offer a lightweight and significantly more economical power distribution solution compared to copper cables.
Rigid Stranded Design: Employs Class 2 compacted stranded aluminum cores, ensuring excellent structural stability for fixed wiring.
Reliable Dual PVC Layers: High-grade PVC insulation and outer sheath provide dependable electrical insulation, moisture proofing, and flame retardancy.
Anti-Corrosion Performance: The heavy-duty PVC jacket formulation effectively insulates the aluminum cores from soil chemicals, acids, and atmospheric moisture.
Application
Industrial Main Supply: Ideal for primary power feed lines, main switchboard connections, and distribution lines in manufacturing plants and warehouses.
Underground Burial Grids: Widely used for fixed installations buried directly underground or laid in concrete cable trenches for local power grids.
Civil Infrastructure: Perfect for long-distance low-voltage power transmission networks in public infrastructure, commercial complexes, and industrial parks.
Cable Trays & Ducts: Suitable for fixed routing through outdoor or indoor cable trays, open air conduits, and dedicated technical shafts.

FAQ
1. What are the economic and structural benefits of specifying NAYY / VLV aluminum cables over copper?
Massive Cost & Weight Optimization:
Our NAYY / VLV aluminum power cable serves as a highly cost-effective alternative to copper main lines, reducing continuous metallurgical expenses by up to 60%. Manufactured utilizing high-purity electrical-grade aluminum, this core configuration drops total cable weight by roughly 40-50%, heavily slashing long-distance maritime shipping fees, easing project logistics, and decreasing installation labor loads on heavy cable trays.
2. How do the technical standards of NAYY, VLV, and descriptive IEC codes align globally?
Cross-Border Nomenclature Framework:
The designations seamlessly mirror equivalent international standards to fit varying utility bidding tenders: ‘NAYY’ directly complies with German VDE 0276 guidelines, widely demanded across Europe and CIS sectors; ‘VLV’ maps strictly to the Chinese National GB/T 12706 standard utilized on China-backed overseas civil infrastructure; while ‘Aluminum/PVC/PVC’ follows the universal standard descriptive language defined by IEC 60502-1 for worldwide project compliance.
3. Why is a dual-layer PVC construction ideal for fixed underground burial distribution grids?
Soil Immunity & Heavy Moisture Protection:
Both the primary internal insulation and the rugged outer protective jacket are formulated using premium-grade, flame-retardant Polyvinyl Chloride (PVC). This dual-layered polymeric matrix acts as an impenetrable shield against chemical runoffs, persistent soil alkalinity, organic acids, and ambient moisture. This heavy-duty protection completely insulates the inner aluminum strands, preventing galvanic deterioration and safeguarding direct-buried or trench layouts for decades.
4. What are the rated voltage limits and thermal performance thresholds for this power line?
Standard Voltage Capacity & Thermal Limits:
Engineered explicitly for low-voltage municipal and commercial power grids, this aluminum line holds an official rating of 0.6/1 kV (600V/1000V). The premium PVC insulation compound safely supports a maximum continuous conductor operating temperature of 70°C under full load scenarios. In the event of emergency grid overloads or brief short-circuit faults, the structure safely withstands sudden high thermal spikes up to 160°C without mechanical rupture.
5. What wholesale core configurations and logistics packaging does ZHONGYI CABLE guarantee?
Rigorous Engineering Logistics & Drum Security:
As a dedicated direct factory supplier, we engineer our NAYY / VLV aluminum main supply lines in multi-core clusters (including 4-core, 5-core, and 3+1 structures) spanning heavy cross-sections from 16 mm² up to 300 mm² and above. To prevent radial deformities or layer shifting during international sea transit, wholesale orders are coiled and secured on reinforced steel-wooden drums, backed by complete Type Test Reports and Routine Factory Test Certificates.
