Sumitomo electrical management (Shanghai) Co., Ltd

Sumitomo Electric industries, founded in 1897, is one of the most famous telecommunication companies in the world. Its optical fiber and cable production and sales have been ranked in the forefront of the world for many years, with an annual output value of about 3 billion US dollars. Sumitomo Electric has more than 200 subsidiaries around the world and nearly 10 branches in China.

Sumitomo Zhengyou (1572-1636) and youweimen (1572-1636) started Sumitomo business in Kyoto, the ancient capital of Japan, with a history of more than 400 years. Sumitomo Electric has the unique copper smelting production experience and technology of Sumitomo family with a long history of nearly 300 years, and integrates and accumulates sharp technology. Sumitomo Electric develops diversified products in the market with high potential. Constantly break through technical boundaries. Especially in the fields of optoelectronics, new raw materials, electronic systems and energy. Sumitomo has invested all over the world. In 1949, the Asia Pacific region invested in production, and export facilities began to be particularly active.

development history

In 1897, Sumitomo Shin copper factory was established. As a business of Sumitomo headquarters, Sumitomo acquired "Nippon Copper Co., Ltd."

On April 1, 1897, Sumitomo copper factory was opened, and began to manufacture copper plate, copper rod and copper wire (bare wire).

1900 began to manufacture silicon copper wire for delivery in Japan's Ministry of delivery

1908 began to make power cables

In 1909, the trial production of communication cable was started. At the same time, the trial production of communication cable was also started.

In 1911, Sumitomo wire manufacturing Institute was established. With the high voltage of transmission line and the improvement and expansion of telephone network caused by hydropower generation, in order to further expand the business scope, the wire manufacturing industry of Sumitomo Shentong plant was stripped off and "Sumitomo wire manufacturing Institute" was established. High voltage underground transmission line and cable (11000v) delivered for the first time in China

A new factory (Osaka production Institute) was opened in 1916. In order to cope with the increasing demand for wires year by year, the factory was relocated to the present Osaka production Institute, and the scale was expanded. Start manufacturing enameled wire

1920 Sumitomo wire manufacturing Co., Ltd. (establishment of the company). In order to introduce the world's highest level of technology, we have carried out technical cooperation with Western Electric Company, an American wire manufacturer, and obtained their investment and transformed it into a company.

In 1931, we began to manufacture super hard alloy tools ("igetaloy"). Initially developed is the wire and cable drawing machine parts (mold) cutting tools. Since then, it has been widely used for various purposes other than wire.

Special wires were made in 1932. Using wire and cable processing technology, we began to manufacture special metal wires such as piano wire for Aeroengine valve spring, which were imported at that time.

In 1939, the company changed its name to "Sumitomo Electric Industry Co., Ltd. (now the company name). In order to expand its business scope to products other than wires, the company was changed to its current name "Sumitomo Electric Industry Co., Ltd.".

In 2004, Eudyna devices (semiconductor equipment business) started business; broadwireless Co., Ltd. (antenna related business) started business; signed the world's first commercial contract of high temperature superconducting cable; the company obtained the order of high temperature superconducting cable system from kepri. As a high temperature superconducting cable for power transmission, it is the first commercial contract in the world. In addition, in July 2006, in the actual verification test of superconducting cable in Albany, New York, the United States, we began to use our company's superconducting cable for power transmission, which is the first time in the world to use superconducting cable for actual underground transmission circuit.

In 2006, we developed a 200Mbps home network PLC modem for Japan. PLC (high-speed power line communication) can build a simple, low-cost and stable home network without new wiring engineering. The company has developed a small, ultra high speed (200Mbps) PLC modem for home user network in Japan.
