Development of Long Span Type Overhead Rigid Conductor Line of Catenary System
IEEJ Transactions on Industry Applications, 1998 An overhead rigid conductor line in a tunnel is free from the fear of disconnection because the contact wire is not tensioned, and it is superior in maintenance saving. In order to introduce this in open sections, we have developed “a long-span-type overhead rigid conductor line of catenary system.” This contact line structure consists of a contact ...

Quarterly Report of RTRI, 2008 In order to adopt rigid conductor lines in tunnels of small sections, it is necessary to install a transition structure just outside the tunnel to allow a smooth pantograph shift between the catenary-type contact line and the rigid conductor line. However, the present transition structure is complicated, has inferior current collection characteristics ...
