Product Specification
| High Light | stranded copper building wire ，PVC insulated single core cable ，FR ES PT panel builder cable | ||
NYA is the VDE name; H07V-R is the CENELEC harmonized name—both mean single-core PVC insulated building wire. Our 70mm² uses Class 2 stranded copper (company standard: ≥10mm² = Class 2), 1.4mm PVC, and is the wire panel builders in Santiago, Lima, Paris and Valencia buy by the coil for busbar jumpers.
Technical Specifications:
· Voltage rating: 450/750V
· Conductor: IEC 60228 Class 2 stranded copper, 70mm² (19×2.1mm)
· Insulation: PVC, available in red, yellow, blue, black, green/yellow
· DC resistance @20°C: ≤0.268 Ω/km
· Insulation thickness: 1.4mm
· Overall diameter: 12.0–13.0mm
· Weight: 660–680 kg/km
· Current capacity: ~215A (in free air, 30°C)
· Short-circuit temp: 160°C (5s)
· Standards: IEC 60227-3
Installation Notes:
The 70mm² size requires proper cable lug crimping—we recommend hydraulic crimping tools for reliable termination. The stranded construction (vs solid) makes it easier to pull through large conduit runs and reduces risk of conductor damage during installation.
Where It's Specified:
Main incoming feeds to distribution boards, generator connection cables, UPS output wiring, and large commercial air conditioning disconnects. Often used as phase or neutral backbone in three-phase panels where individual color-coded single cores are run in parallel through conduit or cable tray.
Manufacturing Strength
Our factory uses 99.9% oxygen-free copper rods and premium PVC compound with consistent extrusion thickness. Every batch undergoes spark testing, conductor resistance testing, and flame retardancy verification. With 15+ years of export experience to Europe, Africa, and Latin America, we understand the documentation and certification requirements of different markets.
