Electric wire industry - densen kougyou (English spelling) electric wire industry

Japanese: 電線工業 - でんせんこうぎょう（英語表記）electric wire industry

An industry that manufactures electric wires and cables for power and communication. Depending on the type of wire produced, it can be broadly divided into bare wire manufacturing, cotton wire/rubber wire manufacturing, synthetic rubber wire manufacturing, magnet wire manufacturing, power cable manufacturing, and communication cable manufacturing. In Japan, it is said that copper wire was first manufactured in Osaka in 1832, and rubber-coated electric wire was manufactured in 1860. Since then, with the rapid spread and development of electrical and communication equipment, various improvements have been made to the quality of the wires, and high-performance electric wires such as optical fiber and extra-high voltage transmission lines have been developed. Recently, research and development of new technologies such as superconductivity has also progressed. It is estimated that there are about 400 major electric wire manufacturing companies, 90% of which are small and medium-sized enterprises. In general, it is an equipment industry and produces a wide variety of products in small quantities, so the management base is in a state of excessive competition, and for this reason many companies are streamlining and diversifying their management.

Japanese:

電力，通信用の電線，電纜を製造する産業。生産する電線の種類により裸線の製造業，綿線・ゴム線製造業，合成ゴム線製造業，巻線製造業，電力ケーブル製造業，通信ケーブル製造業などに大別することができる。日本では天保3 (1832) 年大坂で初めて銅線が製造されたといわれ，安政7 (60) 年にはゴム被覆した電線が製造されている。その後，電気および通信機器などの急速な普及発達とともに，その品質にも種々の改良が加えられ，光ファイバ，超高圧送電線のような高性能の電線などが開発され，近時は超電導などの新技術の研究開発も進んでいる。主要な電線製造会社は約 400社と推定され，その9割を中小企業が占める。一般に装置産業であり，多品種少量生産であることなどから，経営基盤は過当競争状態にあり，このため経営の合理化，多角化を進めている企業が多い。
