Abstract: In a catenary-based transportation system which is provided with integrated power supply equipment having an electricity storage unit which stores electricity regenerated by vehicles traveling by electricity received from a catenary and supplies electricity to the catenary and the other power supply system which is a power supply system different from the electricity storage unit concerned, the performance of a rectifier of the other power supply system is determined based on a power-supplying contribution ratio ? of the other power supply system so that the cost value of the integrated power supply equipment becomes lower than a target cost value.

Abstract: A connector having a frame with an upper arm and a lower arm cantilevered from a center section to form a channel adapted to receive a section of a structural steel member. The frame has a conductor receiving area to receive a conductor therein. The conductor receiving area is located so that when the upper arm and the lower arm are compressed to grip the section of the structural steel member received in the channel, the conductor located in the conductor receiving area is crimped to the frame.
