When 70mm² is oversized and 35mm² is tight, 50mm² H07V-R (NYA) is Class 2 stranded, PVC TI1, 450/750V, IEC 60227-3—boxes leave our plant with meter-marking and color options (rojo/negro/azul/amarillo-verde).
Why 50mm² is a Popular Choice:
· Handles approximately 175A in free air—enough for most 3-phase 22kW–30kW loads at 400V
· Stranded Class 2 construction (19×1.75mm) provides good flexibility for panel dressing
· Easier to terminate than 70mm²—fits standard 50mm² compression lugs
· Lower material cost than 70mm² while covering the majority of commercial load requirements
Detailed Parameters:
· Rated voltage: 450/750V
· Conductor: Class 2 stranded copper, 50mm²
· Insulation: PVC, 1.2mm thickness
· Overall diameter: 10.5–11.5mm
· Weight: 480–500 kg/km
· DC resistance: ≤0.387 Ω/km @20°C
· Test voltage: 2500V AC
· Operating temp: -15°C to +70°C
· Standard: IEC 60227-3
Typical Project Applications:
Feeder from main switchboard to sub-distribution board in commercial buildings, industrial machine tool power connections, HVAC rooftop unit feeds, and solar inverter AC output wiring (within voltage rating). Color-coded per phase for easy identification in multi-core conduit runs.
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.
