[0003] Semi-conductive nylon tape has a certain conductivity, which can evenly distribute the electric field inside the cable, reduce partial discharge and corona phenomenon, and improve the electrical performance and reliability of the cable; Semi-conductive nylon tape can shield external electromagnetic interference, reduce the electromagnetic radiation of the cable to the surrounding environment, and also prevent the influence of external electromagnetic fields on the inside of the cable, protecting the signal transmission inside the cable from interference;
