<strong>Electric</strong> Wire &<br />

Cable, Energy<br />

Ever since its founding, the Group has contributed to the stable supply<br />

of energy in various fields with products such as electric power cables for<br />

electricity transmission and distribution, trolley wires for railways, and magnet<br />

wires used in home appliances, automobiles and other products. With the need<br />

for ever greater use of renewable energy and energy conservation, the Group<br />

is aggressively developing high-temperature superconducting cables and smart<br />

grid technology.<br />

Industrial Materials &<br />

Others<br />

The products of this segment consist of special steel wires that evolved from<br />

copper wire drawing technology and includes prestressed concrete steel, steel<br />

wires for springs, and steel tire cords. Other products include cemented carbide<br />

tools essential for machine processing, crystal boron nitride (CBN) and diamond<br />

cutting tools, sintered machine parts used in automotive and other industries.<br />

These products are based on the Group’s powder metallurgy and super highpressure<br />

press technologies derived from the development of cemented<br />

carbide for copper wire drawing dies. The <strong>Sumitomo</strong> <strong>Electric</strong> Group’s advanced<br />

materials play an active role in a wide range of industries.<br />
