H07V-K (NYAF) 450/750V 1x10mm2 class 5 copper Extra Flexible Single Core PVC Wire for PLC Panel Internal Link

10mm² H07V-K is the sweet spot for control-circuit returns and relay wiring inside enclosures. Class 5 stranding bends by hand and holds shape—no spring-back like solid wire. We supply it in 100m coils with 12-color options for Spanish panel assemblers and Chilean solar BOS vendors.

Key Differences from 16mm²:

· Conductor: Class 5 fine-stranded, 84×0.40mm (10mm²)

· DC resistance: ≤1.83 Ω/km @20°C

· Diameter: 5.5–6.5mm (noticeably thinner, easier to dress in tight panels)

· Weight: 115–125 kg/km

· Current capacity: ~57A (free air)

· More wires per drum = lower unit cost for large panel-building projects

Technical Data:

· Rated voltage: 450/750V

· Insulation: PVC, 0.8mm thickness

· Test voltage: 2500V AC

· Operating temp: -15°C to +70°C

· Flame retardant: IEC 60332-1

· Standard: IEC 60227-5 / H07V-K

Manufacturing Strength:

Our factory produces NYAF on dedicated fine-wire stranding lines that maintain consistent lay length and tension, critical for achieving the flexibility that panel builders demand. Every coil is tested for continuity and insulation resistance before packing.

Application Scenarios:

Control circuit wiring, inter-panel communication cables, relay and timer connections, instrument transformer secondary wiring, and low-power DC control systems inside enclosures. The thin profile makes it ideal for high-density terminal blocks where space is at a premium.
