History
50 EVENTS
Sumitomo Electric Wire and Cable Works established 1911. Despite the remarkable development of the electric power business, the nation was still relied on imports for high-grade goods, and its technologies were immature. Lamenting the situation, Kankichi Yukawa, Director and Manager of Sumitomo Head Office, decided to further accelerate the electrical wire business to benefit both Sumitomo and the nation. In the fall of that year, Sumitomo Electric succeeded in the practical application of lead-coated power cables for the first time in Japan, demonstrating a further leap in technology. These cables were used for power transmission from Kyoto Dento's thermal power plant in Fushimi to Kyoto City.
Although the war had ended, plants had been hit hard by air strikes and were in a desperate situation. After expressing appreciation to the employees for all their past efforts, then-President Sadao Bekku said that Japan must now rebuild itself as a cultural nation, and that Sumitomo Electric's products are essential to achieving this, and therefore, the company must strive to manufacture products for achieving its mission in whatever form the company would take. In addition to electric wires, Sumitomo Electric also manufactured daily necessities, and other agricultural tools, using materials on hand.
Typhoon Jane was a large typhoon that hit Osaka in September 1950, inflicting damage with 336 people dead, 500,000 victims, and 15,000 houses collapsing mainly in the Kansai region. The western plant of Osaka Works was flooded by water. Aluminum overhead transmission cables bound for India were submerged by floodwaters. Although the products could have been made usable by washing them, management decided to re-make them all, with no thought of gain. This clearly shows our traditional spirit of devoting ourselves wholeheartedly to supplying quality products and placing prime importance on reliability.
Succeeded in achieving domestic production of oil-tempered wire.
