The development history of the world wire and cable
2019-02-27
In 500 BC, Greece discovered friction electricity.
In 1200, Italy set off a Renaissance spread across Europe, the rise of modern natural science.
In 1752, the American scientist Franklin invented the lightning rod and the wire grounding, from then on, the wire began to apply.
In 1826, the German physicist Ohm discovered Ohm's law and determined the conductivity of metals.
In 1851, Britain laid a submarine cable across the English Channel. Since then, the European and American countries have developed.
In 1879, Edison invented the incandescent electric lamp, made of jute asphalt insulated power cable, laid in New York.
In 1927, the United States first invented PVC insulation. During the Second World War, Germany developed a large number of PVC cables in order to find a substitute for rubber, a strategic material.
In 1952, irradiated cross-linked polyethylene was used to make wires; chemical cross-linking method and silane cross-linking method were successively invented; 500kV cross-linked power cables were developed in Japan and opened in Tokyo.
In 1995, the American Superconductor Company built the first 30m long high temperature superconducting cable line.
In 1871, the British Dadong Company laid a Gutabo glue insulated submarine cable between Shanghai, China and Nagasaki, Japan.
In 1936, Yunnan Kunming Cable Factory was established and produced China's first cable in the same year.
In 1983, Shanghai Cable, Shenyang Cable and Shanghai Cable Institute jointly developed 500kV oil-filled cables and accessories, which have been put into operation since then.
70 years, China began to produce cross-linked cable, mainly: Shanghai, Shenyang, Tianjin and Xiangtan cable factory.
In 1993, China Wire and Cable Joint Venture Company first contracted 132kV oil-filled cable lines in Karachi.
In 2004, the 30m, 35kV and 2kA high-temperature superconducting cables developed by Beijing Yingna Superconducting Technology Co., Ltd. were put into trial operation in Yunnan Phuket Substation.
