Abstract
The invention discloses a light total carbon cable and a preparation method. The cable consists of an insulating protection layer, a light shielding layer, thin insulating sleeves and inner conductors. The thin insulating sleeves are arranged outside the inner conductors. The light shielding layer is arranged outside a number of inner conductors which are mutually twisted. The light shielding layer is coated by the insulating protection layer. The inner conductors are formed by intertwining more than one conductive unit. Each conductive unit is metal fiber with the diameter of 10nm to 100um, wherein the metal fiber comprises non metallic fiber and a conductive layer, wherein the conductive layer is arranged outside the non metal fiber, and the thickness is 10nm to 50um. The high strength non metal fiber is directly coated by the conductive layers, which keeps the fiber flexibility of the non metallic fiber, effectively improves the conductivity of the metal fiber, and improves the signal transmission capacity of the cable. The cable has the advantages of simple operation and easy large-scale industrial production. The cable is used to replace a conventional copper core cable. The winding and folding resistance is greatly improved. The weight of the cable is greatly reduced.
