SFT-50-0.6

The SFT series of steel cables, the outer conductor is seamless copper tube and aluminum tube structure. Due to the shield .Is fully enclosed structure, so the cable has a optimal shielding performance and minimal outer conductor loss, the use of higher frequencies .And good performance index within the full frequency range. Characteristic impedance of 50 Ω, 75 Ω, 10 Ω, 25 Ωand so on. Electrical performance, the use of high frequency, voltage standing wave ratio is small, high shielding efficiency. Mechanical performance, strong tensile strength and bending formability, but in use process should prevent bending .Radius is too small and the second curved outer conductor damage Environmental resistance, cable environment adaptability is very strong, usually according to the specific use environment of different plating Layer of protection.
