The course of the history of wire and cable

The course of the history of wire and cable
    History for future generations is not just a recall, more importantly, to achieve enlightenment in understanding: Only continuous innovation, have real s vitality.
    History has proven that the cable wire product development is closely linked with social progress, a major technological breakthrough in a particular area will promote social mutations.
    First, that "power" can be transmitted along the wire (1800)
    500 BC, the Greek Thales found that friction power.
    In 1729, the British Gray found "power" can be transmitted along the wire, the human with the "conductor" concept.
    1740, the French conductor and the insulation provided definition.
    In 1744, the German Winkler wire transfer to the spark distance, declaring the birth of the wire.
    In 1752, Franklin invented the lightning rod Americans, and ground wire, this is the first practical wire.
    In 1799, Italian inventor volt battery, get a continuous current.
    Second, the "telegraph" the invention of the telegraph cable to promote the development, application (1875 years ago)
    The early nineteenth century, the Danish Oersted, Faraday Britain, Germany, Ohm, the United States and many other European and American physicist Henry continued discovery and creation of the modern electricity, many of the basic theory of electromagnetism, for the future of electric power, information transmission opened the floodgates.
    In 1833, Gauss and Weber made the first electromagnetic telegraph pointer, for 1 km-long line, with six years.
    1835, the United States Morse invented the telegraph wire, to promote the development of the communications cable.
    In 1839, Cook, Wheatstone in London, built the first telegraph line 21 kilometers long. New York Harbor in 1841, laying the rubber insulation of submarine telegraph cables.
    1851, the British laid a submarine cable across the English Channel. Since then, the United States and Europe competing development; three decades, almost all over the telegraph cable connected the countries major cities. To 1920, the British Commonwealth countries completed the connection, telegraph cable networks around the world, led the United States, Japan and other countries laying of submarine telegraph cable to a climax.
    1871, the great British East Company in China between Shanghai and Nagasaki, Japan, the laying of a submarine telegraph cable rubber insulation.
    Third, cable products everywhere in the three areas (1980)
    (A) wire
    1,1875, the American Henry made the first insulating paint and fiber patents. The United States in 1902, GE made acetate enameled; oily magnet wire made in 1909; 1925 line made of polyvinyl formal; acetal enameled wire was invented in 1938; polyester enameled wire was invented in 1954.
    2, Japan in 1939 developed a glass enameled wire; 1954 enameled wire made of silicone. Germany in 1940, made of polyurethane enameled wire.
    3, the United States Dodge in 1951 invented the self-adhesive magnet wire; 1963, a compound made of enameled wire.
    4, the United States in 1957, DuPont invented the acrylic magnet wire; made in 1961, polyester-imide enameled magnet wire and polyimide; made of polyamide 1964 - imide enamelled wire.
    5, 1966, Shanghai Electric Cable Research Institute made of polyimide in enameled wire; made in 1970 Polyamide - imide enamelled wire.
    (B) the communication cable
    1,1876, the United States Bell invented the telephone cable, USA local communication cable. 1878, the United States between New York and Boston opened the first long-distance cable road.
    WE 1889 U.S. companies began mass production of paper tape around the insulated lead covered local communication cable.
    1891 English Channel, then laying the first undersea cable.
    Britain in 1898 between London and Birmingham, the laying of a 46-km four-lane consisting of 19 long-distance communications cables; to 1938 it was changed with carrier communication.
    2,1921, the United States and Cuba between the laying of a submarine, then the first coaxial cable.
    In 1932, between Britain and Belgium, laying the first submarine coaxial cable carrier transmission.
    In 1936, German-made broadband coaxial cable for transmitting television.
    In 1939, Germany, the United States has developed a polyethylene material, used in various communication cables.
    In 1944, the United States and France, the distance between the laying of the longest (100 miles) undersea cable.
    In 1949, the United States made public the antenna cable television (CATV).
    In 1950, the U.S. made plastic (PE) composite aluminum sheath wrinkles telephone cables.
    3,1956, the United Kingdom, the United States, Plus Three cooperation in laying the first transatlantic telephone cable is symmetrical, length of 4300 km; 1959, the United States, France, Plus Three cooperation in laying a second transatlantic submarine communications cables (coaxial type) ... .... To 1976, a total of 6 laying undersea communications cable across the Atlantic. Since then, all waters in the Atlantic and another has laid a large number of submarine communications cables, so that regions of the world, all the smooth transfer of information between countries.
    October 4,1976, the submarine cable system between Japan and the opening of 480 sessions.
    (C) power system with cable
    1,1879, the United States Edison invented the incandescent lamp, made of yellow? Asphalt insulated power cable, laid in New York.
    In 1887, the United States Brooks with low viscosity insulating oil impregnated paper insulation of power cables as.
    In 1888, the British ferranti made of oil impregnated paper insulated 10KV cables (two cores, with core-type).
    In 1890, the United States made three core oil impregnated paper insulated power cables.
    In 1893, the company began producing paper BICC UK power cable.
    In 1910, in Berlin, Germany, 30KV three-core cables laid in 1911, laying 60KV single-core cable.
    In 1911, the Japanese paper production 10KV power cable
