What Are Cables, Wires?
Cables and wires are the fundamental conductors used to create electrical connections in electronic systems. The category includes hookup wire (solid and stranded), ribbon cable, coaxial cable, shielded cable, speaker wire, silicone wire (heat-resistant), and specialty wires like enameled magnet wire for inductors and transformers. LCSC Electronics stocks 8,000+ cable and wire SKUs from 80+ manufacturers.
Cables, Wires — Definition and Sub-Categories
A wire is a single electrical conductor, while a cable is an assembly of two or more wires within a common jacket or sheath. Wires and cables are characterized by conductor material (copper, tinned copper, aluminum), insulation type (PVC, PTFE, silicone, polyethylene), wire gauge (AWG or mm²), voltage rating, and environmental specifications.

How to Choose: Cables, Wires Selection Guide
Select wire gauge based on current capacity: 22 AWG handles about 7A, 18 AWG handles about 16A (in free air). For signal wiring, 22–28 AWG is standard. For power distribution, size the wire for your current with appropriate derating. Choose stranded wire for flexibility (harnesses, moving parts) and solid wire for breadboarding and point-to-point connections. Silicone-insulated wire is essential for high-temperature environments (near heatsinks, inside enclosures with poor airflow). Use shielded cable for sensitive analog signals in noisy environments.

Frequently Asked Questions
Q: What AWG wire gauge should I use?
For signal wiring: 22–28 AWG. For moderate power (1–5A): 20–22 AWG. For high power (5–15A): 16–18 AWG. For very high power (>15A): 12–14 AWG or larger. Always verify current capacity using a wire gauge chart and derate for enclosed/bundled installations.
Q: What is the difference between solid and stranded wire?
Solid wire has a single conductor — it’s stiffer, holds shape well, and is ideal for breadboarding and point-to-point connections. Stranded wire has many thin conductors twisted together — it’s flexible, resists fatigue from repeated bending, and is standard for wire harnesses and moving connections.
Q: When should I use shielded cable?
Use shielded cable when carrying sensitive analog signals (audio, sensor readings) in electrically noisy environments (near motors, switching power supplies, digital buses). The shield blocks external electromagnetic interference from corrupting the signal. Ground the shield at one end to prevent ground loops.
Q: What is magnet wire used for?
Magnet wire (enameled wire) has a thin lacquer insulation instead of plastic, allowing tight coil winding. It’s used to wind inductors, transformers, motors, solenoids, and relays. The enamel insulation is rated by temperature class (130°C to 220°C typical).
