Overhead rigid conductor line in 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 section, we have developed "a long span type overhead rigid conductor line of catenary system". This contact line structure consists of contact wire of no tension attached to the supporter which has a small drag coefficient hanged by the messenger wire. In this time, we have developed "square supporter" to make the drag smaller and put it to various tests with support point interval 50m and 10m. As the testing results, the contact loss is 1_??_2% at 130km/h, and this overhead rigid conductor line can collect the current with stability equal to the normal catenary system.
