- A transmission-line cable with a length of 2 km consists of 19 strands of identical copper conductors, each 1.5 mm in diameter. Because of the twist of the strands, the actual length of each conductor is increased by 5. Determine the resistance of the cable if the resistivity of copper is 1.72-cm at 20C.Show that VSWR for a transmission line will have values between 1 and infinity.A transmission line is supported from two towers at heights of 40 m and 58 m above ground level, the horizontal distance between the towers being 300 m. If the maximum allowable tension is 2500 kg, find the minimum clearance and the clearance at a point mid-way between the towers. Weight of conductor is 1 kg/m.
