The catenary line and feeder line installed on same electrical pole in opened place of AC electrical rail-road. The Electrical pole has receive a different weight from the catenary line and feeder line. So we have designed the Feeder supporting metal with new shape and material based on this fact. And then we have examined the stability of Feeder supporting metal designed a steel pipe by FEM program. New steel pipe compared with existing steel pipe on a economy respect. That result give proof the stability and economy as feeder supporting steel. There-fore this device have a basic of Value Engineering, so we have the need of reflection to design as a device of new electrical pole.
