With the USB 3.0 extension cable from kabelmeister®, you can quickly and easily extend your existing USB cable. In doing so, you can rely on the proven Kabelmeister® quality. For our USB 3.0 cables, we only use high-quality cable material tested by UL. The use of modern production facilities, standardized processes and high-quality materials ensures consistently high product processing quality. High-quality cable construction The conductors of our USB cables are made of copper (CU) and are double-shielded (braided and foil shielding). The AWG28 data lines, shielded in film, are twisted in pairs (twisted pair) and ensure a data transfer rate of up to 5 Gbit/s (super speed). The copper wires for the power supply (USB bus power) are thicker with AWG24. For reasons of cost, other manufacturers sometimes use thinner cores or copper-plated aluminum (CCA) or steel copper (CCS) as conductor material. This results in a significant
