JEC’s Technology
Realize Your Dreams

Welcome to

The Japan Electrical Consulting Co., Ltd. (JEC) pursues overseas projects for consulting service in all electrical systems of transportation infrastructures.
In our history of overseas projects over 50 years, we have been designing, supervising and consulting of substation, overhead catenary, power distribution, signaling and telecommunication systems for railway construction and improvement projects in 56 countries.
For the urban transportation system in many countries, eco-friendly public transportation system (LRT, MRT, Monorail., etc.) which is the most suitable for the site is being introduced, and we have more opportunities to provide technologies.

Overseas achievements

We have excellent track records of success for not only the railways technology but also the highway networks and etc.

Special Assistance for Project Implementation (SAPI) for Panama Metropolitan Area Urban Transportation Line 3 Development Project, Panama

The project in Panama is to cope with the growing demand of transportation and to ease the traffic congestion in the Panama capital region.
Construction of the monorail from the west bank region of the Panama canal to the Panama capital region is planned, namely the Panama Metro No.3 project.

The project has started by the contract signing made on 29 August 2018 between the Employer and the Consultant.

The route of the line crosses Panama Canal and its elevation varies a lot from the starting point to the end. The large capacity of the transportation is also expected. Hence, Japanese style straddled type monorail is adopted.
The length is 27 km and the line has 14 stations. JEC, as the expert firm of electrical system design, conducted planning and designing of the total electrical system for 1 number of a receiving substation, 9 numbers of feeding substation, and 1 number of a depot substation.
