The Cable Materials Research Laboratory promotes research and development to provide precise solutions to customer needs, with a focus on technologies in the following seven fields: covering material, copper alloy, in-vehicle installation, material processing, high-speed transmission, analytics, and analysis. We place particular emphasis on research and development of unprecedented high value-added cables for use in railways, medicine, and electronic components.

Electric wires and cables must not only serve their purpose of transmitting energy and information, but must also offer added value that provides safety and convenience, such as being highly flame-retardant, being resistant to high temperatures, and having a smooth surface. For example, wires and cables used inside railway vehicles must have high flame-retardant capabilities and durability, while also being easy to work with so that they can be installed in confined spaces within a short period of time. Wires and cables used for ultrasound diagnostic equipment and industrial robots must have strong flexibility and be able to endure repeated bending movements.
In addition to meeting the above needs, it is also important to develop wires and cables that achieve efficiency and low costs. Up to now, we have been developing our products by trial and error based on the knowledge and experience that we have accumulated thus far, but the Cable Materials Research Laboratory has now begun efforts in research and development that also make use of MI (Materials Informatics).
