The superconducting technologies that Furukawa Electric possesses are likely to offer excellent solutions to environmental and energy issues.

Feature of smart grid

HTS power cable

Low loss and compact power transmission cable

DC HTS cable

Long-distance transmission cable


Fault current limiter for short circuit accident

A fault current limiter (FCL) that uses superconducting materials is a power device that suppresses fault currents.

FCL will be an essential element in the smart grid, maintaining its reliability and improving its resilience and flexibility.
