Energy : Hitachi Cable

The Hitachi Cable Group contributes to society through its technology to "deliver" energy such as wind power generation, atomic power generation, solar power generation and other power generation operations in addition to next-generation clean energy.

Contributing to a steady electrical supply

Products for power generation and transmission facilities

High-voltage electricity generated at a power plant is transformed at a substation and sent to factories, buildings and dwellings. The Hitachi Cable Group offers a wide range of products for total power generation and supplies items such as magnet wire used in generators and transformers at wind generation plants and substations, radiation and flame-resistant cables used in atomic power plants and high-voltage, large capacity electric wires and cables* including overhead and underground power lines (CV cables).

* High-voltage electric wires and cables are manufactured and sold by J-Power Systems Corp.

Clean solar energy

Solder-plated rectangular wires for solar batteries

Solder-plated rectangular wires connect the cells of solar batteries and serve as conductors to collect generated power. Lead-free type solders are used in consideration of the environment.

Eco-friendly products

Thermofin tube

Ecocute*1 is a home water heater that boils water by using a heat pump technology*2 to generate heat from air.
Compared with combustion water heaters, this product is expected to be more energy-saving and is also ecoconscious as it uses a natural refrigerant (CO₂). The thermofin tube of Hitachi Cable is used as heat exchanger tubes in air heat exchangers of Ecocute.

*2 A technology to efficiently increase and decrease the temperature by delivering the heat in the air to a refrigerant via a heat exchanger and compressing or expanding the refrigerant.

Rolled copper foils for lithium ion batteries

Lithium ion batteries are more environmentally friendly than conventional batteries. The Hitachi Cable Group builds rolled copper foil for lithium ion batteries from raw materials up to finished products, anticipating their use in high-performance lithium ion batteries to be used for hybrid cars and electric vehicles.

Contributing to next-generation clean energy
~Superconductive cables for ITER (International Thermonuclear Experimental Reactor)~

Superconductive cables of the Hitachi Cable Group are employed for ITER (an international project to design and build an experimental fusion reactor). This project is an ultra-largescale international project to achieve the first experimental nuclear fusion reactor in human history in order to verify that nuclear fusion energy is scientifically and technologically viable for peaceful purposes, with the aim of beginning operations in 2018*. As nuclear fusion energy does not emit CO₂, it is expected to be a next-generation clean energy. As nuclear fusion is induced in the experimental reactor, strong magnetic fields are used to confine ultra-high-temperature plasma of more than 100 million degrees Celsius. In order to maintain such magnetic fields for a long period of time, superconductive wires, "Toroidal Magnetic Coils" are used. The Hitachi Cable Group supplies superconductive wires (Nb3Sn) used in the coils, and has recently introduced wire-stranding machines for manufacturing superconductive cables for ITER, to assure stable quality and mass production.
Our Group continues to aggressively promote cable and wire R&D to contribute to the progress of newgeneration clean energy and to expand and strengthen our superconductive product business.
