Abstract

PURPOSE: To reduce voltage drop on power supply by using a concentric cable for power supply to a trolley wire, arranging the cable along the trolley wire, and supplying power to the wire at a middle point between stations.
CONSTITUTION: A concentric cable 13 is arranged along a trolley wire 12 and power is supplied to the wire 12 at a middle point X between stations. For example, when a 500 mm2 concentric cable 13 is arranged along the trolley wire 12 and poewer is supplied at the middle point X, the combined impedance Z will be 0.0341 + j0.0227 (Ω/kg) and the voltage drop Vd at the point X will be 49.7V.
