6N. USB Grandio 2.0

Conductor composition

• Signal line :
  • Ultra-high purity 6N copper (6NCu) : 99.9999% purity, extremely low resistance and signal loss, suitable for high-fidelity signal transmission.
  • High-purity oxygen-free copper (PCUHD) : High-ductility pure copper, optimizing the clarity and stability of signal transmission.
  • Pure silver coated OFC : Silver plating on oxygen-free copper surface enhances high-frequency signal transmission performance, reduces skin effect, and is suitable for audio signals.
• Power cord :
  • High-purity oxygen-free copper (OFC) : Low oxygen content reduces resistance and oxidation, making it suitable for low-power power transmission.
• Analysis : The signal cable uses a combination of three high-performance conductors to emphasize high-fidelity audio transmission; the power cable uses a single OFC, suitable for low-power supply requirements.

structure

• 2-core signal cable + 2-core power cable, 4-core configuration : The composite design integrates signal and power lines into a single cable, suitable for scenarios with limited space or where simplified wiring is required.
• Conductor specifications :
  • Signal line: 0.105 mm² (≈AWG27) × 2, suitable for low current and high precision signal transmission.
  • Power cord: 0.226 mm² ×2, suitable for low-power power transmission, with a current capacity lower than the previous power cord's 3.0 mm² ×2.
• Analysis : The small cross-sectional area conductor indicates that this wire is suitable for low-power equipment or short-distance transmission.

Sheath and insulation

• Outer sheath : PVC (RoHS compliant) + two-color high-strength nylon weave. The double-layer sheath enhances durability and aesthetics, making it suitable for frequent movement or high-end equipment.
• Insulation layer : High-purity polyethylene with low dielectric constant, reducing signal attenuation and suitable for high-frequency signal transmission.
• Shielding layer :
  • Inner layer: Signal lines are individually shielded with aluminum foil to reduce crosstalk between signals.
  • Outer layer: Double shielding of aluminum foil and high-purity copper braid, providing strong resistance to electromagnetic interference (EMI) and radio frequency interference (RFI).
• Filling material : natural cotton thread, which increases flexibility and structural stability and reduces micro-vibration interference.
• Analysis : Double shielding and high-quality insulation ensure the stability of signal and power transmission, making it suitable for high-fidelity audio equipment or precision devices.

outer diameter

• 5.8 mm : The thinner, rounded design facilitates wiring and is suitable for compact devices or portable applications.
