Single Core H07V-R NYA 450/750V 1x50mm2 PVC Insulated Copper Wire for Sub Board Feeder Electrical Wholesalers

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.
