About
We entered into a business partnership with the Daihen Group, which has been working to develop power distribution equipment that meets the resource saving, energy saving, environmental harmony, and various other needs of society. We offer a lineup of extra-high-voltage power distribution equipment for large-scale plants and buildings with large load capacities.
For medium-sized buildings, we propose highly reliable models with optimal designs suited to the application. We propose total solutions, including equipment compatible with the latest communication functions, to meet the need for effective use of space, reduction in equipment costs, and operating expenses through downsizing.

Configuration Example
- 03. Generator System
- 04. Power Distribution System
-
❶ Gas-insulated Switchgear (GIS)
Houses extra-high-voltage (84/72 kV) equipment in a gas (SF6)-insulated container, resulting in a great reduction in space. A cubicle-type GIS is also provided.
-
❷ Extra-high-voltage Transformer
Reduced CO2 emissions and electricity bill thanks to a low-loss design.
-
❸ Transformer Secondary Board and Feeder Board
Supply power to the load side. Implement equipment operation, measurement, and accident protection.
-
❹ Energy Storage System
Supplies electricity stored at night, etc., during peak demand hours and in emergencies. The system contributes to business continuity by supplying power to important loads in the event of a disaster.
-
❺ Extra-high-voltage Monitoring Panel
Monitors, controls, and measures extra-high-voltage equipment.
-
❻ Capacitor and Reactor Panel
Implement automatic power factor correction at a low power factor.
-
❼ Generator
Supplies power to important loads during disasters to help with business continuity.
-
❽ Power Monitoring System
Centrally manages operating status, measurement data, and equipment control for power distribution systems. Contributes to the reduction of electricity bills, energy savings, and labor savings in administrative work thanks to its demand monitoring function.
