Electric wire is a fundamental part of residential, commercial, and light industrial electrical systems. It carries current between power sources, distribution panels, lighting equipment, appliances, instruments, motors, and other electrical devices.
For installations involving bends, compact routing, moving appliances, or equipment connections, a flexible electric wire can provide easier handling than a rigid solid conductor. Its stranded copper construction allows the wire to bend more easily while maintaining dependable electrical performance.
Jianyun Cable supplies NYAF and NYYHY-F flexible electric wire with stranded copper conductors and PVC insulation. The product is suitable for indoor building wiring, domestic electrical appliances, instruments, lighting installations, and applications where flexible routing is required.
Recommended Electric Wire:
NYAF/NYYHY-F Flexible Electric Wire from Jianyun CableFlexible electric wire is an insulated conductor manufactured with multiple fine copper strands instead of one solid conductor. The strands work together to carry electrical current while allowing the wire to bend and follow more complex installation routes.
PVC-insulated flexible wire is commonly used in electrical cabinets, domestic appliances, lighting equipment, small motors, measuring instruments, and indoor building connections. Depending on the model, the wire may be supplied as a single conductor, flat twin cable, twisted cable, or multi-core sheathed cable.
The correct wire structure should be selected according to voltage rating, current load, installation method, conductor size, bending requirement, operating temperature, and applicable electrical standards.
| Component | Main Function |
|---|---|
| Stranded copper conductor | Carries electrical current while providing flexibility |
| Fine copper strands | Allow easier bending and routing around equipment |
| PVC insulation | Provides electrical separation and general environmental protection |
| Optional PVC outer sheath | Protects multi-core or parallel conductors against wear and moisture |
| Color identification | Helps installers identify circuits, phases, neutral, and protective conductors |
| Advantage | Practical Benefit |
|---|---|
| Flexible conductor structure | Simplifies installation in cabinets, appliances, and compact spaces |
| Copper conductivity | Supports stable and efficient current transmission |
| PVC insulation | Provides reliable insulation for general indoor applications |
| Multiple cable structures | Supports single-core, twin, twisted, flat, and sheathed installations |
| Chemical stability | Provides resistance to common acids, alkalis, grease, and solvents |
| Custom colors | Supports circuit identification and project-specific requirements |
Flexible electric wire is frequently selected for indoor installations where easy routing, repeated handling, or compact electrical connections are required.
| Model | Construction | Typical Application |
|---|---|---|
| RV | Copper conductor with PVC insulation | Flexible single-core electrical connections |
| RVB | Flat PVC-insulated flexible wire | Light-duty appliances and indoor connections |
| RVS | Twisted PVC-insulated flexible wire | Lighting, control, and low-voltage connection circuits |
| RVV | PVC-insulated and PVC-sheathed flexible cable | Appliances, tools, and equipment connections |
| RVVB | Flat PVC-insulated and sheathed flexible cable | Indoor parallel wiring and light-duty equipment |
| RV-90 | Heat-resistant PVC flexible wire | Installations requiring increased temperature resistance |
| Feature | Flexible Electric Wire | Solid Electric Wire |
|---|---|---|
| Conductor construction | Multiple fine copper strands | One solid copper conductor |
| Flexibility | High | Lower |
| Routing | Easy to install around bends and equipment | Best for straight and permanent routes |
| Typical use | Appliances, cabinets, motors, and flexible connections | Fixed building wiring and conduit runs |
| Terminal preparation | May require ferrules or suitable terminals | Simple termination for many fixed installations |
| Feature | Single-Core Wire | Multi-Core Cable |
|---|---|---|
| Construction | One insulated conductor | Two or more insulated conductors under one sheath |
| Installation | Suitable for panels, conduits, and internal wiring | Suitable for appliances and complete equipment connections |
| Protection | Individual PVC insulation | Individual insulation plus an outer sheath |
| Typical selection | Control cabinets and internal equipment wiring | Portable devices, appliances, and power cords |
Electric wire selection should be based on the electrical load and installation conditions rather than conductor size alone. An incorrect wire may increase voltage drop, heat generation, or connection problems.
| Selection Factor | Recommendation |
|---|---|
| Rated voltage | Choose 300/500V or 450/750V according to the electrical system |
| Load current | Select conductor size according to the continuous operating current |
| Cable length | Check allowable voltage drop for longer circuits |
| Flexibility | Use fine-stranded conductors for equipment, bends, and movable connections |
| Operating temperature | Confirm standard or heat-resistant insulation according to the environment |
| Installation method | Consider appliance wiring, conduit, panel, indoor building, or equipment connection |
| Bending radius | Follow the minimum bending requirement for the selected cable diameter |
| Applicable standard | Confirm IEC, BS, DIN, or project-specific requirements |
| Specification | Available Option |
