AI Technical Summary
In existing technologies, the tinned copper wire braided tape and the cross skeleton are prone to loosening during the cable wrapping process, which affects the electrical performance of the cable. In addition, the amount of copper wire used is large, resulting in high cost.
It adopts a cross-shaped skeleton design, with power twisted pairs and communication twisted pairs twisted in opposite directions. Combined with folded aluminum-plastic composite tape and tinned copper wire braided tape, it forms a continuous conductive layer and shielding layer, reducing signal interference and saving copper wire.
It achieves high conductivity and low cost cable, enhances electrical performance and structural stability, effectively prevents external electromagnetic interference, and meets the standard of Category 6e shielded data cable.
