Helical shielded twisted pair data cable, and, process of preparing a helical twisted pair data cable

摘要

"HELICOIDAL ARMORED TWISTED DATA CABLE, AND, PROCESS OF PREPARING A HELICIDAL TWISTED PAIR DATA CABLE". The invention relates to a high performance twisted pair data cable (20), which has an impedance standard deviation of less than 3.5 when the standard deviation is calculated around an average impedance of 50 to 200 Ohms and, preferably, 90 to 110 Ohms. The twisted pair is helically wrapped with a metal shielding tape (16) with a tension that provides a hollow space of less than 25% cross-section and, preferably, less than 18% of the cross-sectional area of the cable. shielded twisted pair. The tape is helically wrapped with an overlap of 30 - 45% and at an angle of 35 - 45 198 with respect to the longitudinal axis of the cable. The cable has a capacity of up to 600 MHz.
