Conductor: Tinned annealed copper, fine-stranded structure.  
Key Wire Pairs: Consistent with UL2501, including:  
1. USB 2.0 differential pair (D+/D-)  
2. USB 3.0 SuperSpeed TX differential pair (SSTX+/SSTX-)  
3. USB 3.0 SuperSpeed RX differential pair (SSRX+/SSRX-)  
4. Power line (VBUS) and ground line (GND)  
Insulation Material: High-density polyethylene or foamed polyethylene, used to achieve 90Ω differential impedance.  
Wire Pair Structure: Four differential pairs, identical in structure to UL2501, employing layered independent shielding.  
Shielding Structure: Multi-layer shielding:  
• Each SuperSpeed differential pair has independent aluminum foil shielding.  
• Overall braided copper mesh shielding (typically ≥65% coverage).  
Sheath: Polyvinyl chloride (PVC) or flame-retardant polyolefin.  
Characteristic Impedance: Differential impedance: 90Ω ±15% (for SuperSpeed pairs).  
Rated Voltage:30V DC (VBUS power line).  
Long-term Operating Temperature:** 60°C to 80°C.  
Data Transfer Rate: USB 3.0: 5 Gbps (SuperSpeed); USB 2.0: 480 Mbps.  
Maximum Length: Recommended ≤3 meters.  
DC Resistance: Strict requirements for VBUS and GND conductors to ensure power delivery capability (900mA @ 5V).
