SHC-Seamless Al Tube-12C
The shielding layer is made of welded seamless aluminum tubes, which significantly improves shielding efficiency and signal transmission quality and also enhances the mechanical strength and life of the cable
By using aluminum tube as the outer conductor, it achieves about half the weight compared to the oxygen-free copper tube. This series is a good choice to reduce unit weight.
Taking full advantage of aluminum, you enjoy the softness on bending. On designing and assembly situation, it is possible to use something like a flexible cable.
