| Voltage Rating | 300 V (general), 600 V (high‑voltage class) |
| Resistance (Ω/1000 ft) | 6.385 Ω |
| Conductor Material | Oxygen‑Free Copper (99.99 %) |
| Insulation Types | PVC, XLPE, PTFE, Silicone (custom) |
| Certifications | CE, UL, RoHS, ISO 9001, ISO 14001 |
Audio Manufacturing (OEM): A U.S. speaker‑system maker reduced internal wiring waste by 22 % after switching to our 18 AWG wire with a verified 10 A ampacity, passing all IEC‑60228 tests on the first trial.

Medical Device Assemblies: For a portable ECG unit, our custom‑tinned 18 AWG cable met the FDA 21 CFR 820 requirements, enabling a 30 % faster time‑to‑market.
Industrial Automation: A robotics integrator used our high‑temperature XLPE‑insulated 18 AWG wire in a 12 V, 8 A drive circuit, achieving 15 °C lower operating temperature versus competitor parts.
John M., Procurement Manager – SoundWave Audio (USA)
“Switching to Xinchangda’s 18 AWG wire cut our material cost by **27 %** and the ampacity data matched our design simulations perfectly. Delivery was on‑time, and the technical team helped us certify the wire for UL‑94.”
Linda S., Senior Engineer – MedTech Solutions (Canada)
“The custom‑tinned version met our ISO‑13485 audit without extra testing. We appreciated the fast 5‑day sample turnaround.”
Ahmed K., Operations Director – RoboFlex Industries (UAE)
“High‑temperature XLPE insulation allowed us to run 8 A continuously at 70 °C, reducing heat‑related failures by **31 %**.”
Compliance & Certifications: CE, UL, FCC, GS, CB, RoHS, VDE, SAA, ISO 9001, ISO 14001, ISO 45001, HACCP/GMP, IPPC.
According to the 2023 NEC and IEC‑60228, 18 AWG copper with PVC insulation is rated for **10 A** at a 60 °C ambient temperature. If you use XLPE insulation, the rating can safely increase to **12 A** under the same conditions.
Yes. Our R&D engineers will analyze your voltage, temperature, and conduit fill data and deliver a tailor‑made ampacity chart within 48 hours, fully referenced to NEC 2023 and IEC standards.
Standard MOQ is **500 pcs** for basic PVC‑insulated wire. For custom colors, enamel finishes, or special insulation (e.g., PTFE), the MOQ starts at **2,000 pcs**.
We partner with DHL, UPS, and FedEx for door‑to‑door service. For bulk orders (>20 kpcs) we offer ocean freight (FCL/LCL) with **FOB Shenzhen** pricing. All shipments are insured and tracked in real time.
Our Technical Service Center provides a 24/7 hotline, on‑site failure analysis (within 72 h for major accounts), and a 12‑month warranty covering material defects and ampacity mismatches.
Limited‑time offer: Order before June 30 2026 and receive a **free 1 kg sample** plus **30 % off** the first 5 kpcs.
