The manufacture of copper wire rods dates back to the founding of Sumitomo Electric. The copper wire rods have been used as raw materials for a number of products.
For what purposes are copper wire rods used?
The Sumitomo Electric Group uses copper wire rods to develop and produce its key products. Typical examples include ultra-high voltage, large capacity underground and submarine cables; wire harnesses that function as the nerves and veins of automobiles; magnet wires that are used for various electronic parts; residential cables used for house wiring; contact wires used for supplying electric power to trains; and ultra-thin coaxial cables consisting of wires with a diameter of 0.1 mm or less that are drawn from copper wire rods 8 mm in diameter.
