The use of power cables has been more than 100 years old. In 1879, American inventor Edison T.A. in the brass wrapping and the penetration of jute in an iron pipe, and then filled with asphalt mixture made of cable. He laid the cable in New York and created an underground transmission. The following year, Callender, the British man, invented the insulated power cable of the asphalt impregnated paper. In 1889, the British S.Z. Ferranti laid between London and Deptford 10 thousand volt oil paper insulated cable. In 1908, the UK built a 20 thousand volt cable network. Power cables are becoming more and more widely used. In 1911, Germany laid a 60 thousand volt high voltage cable and started the development of high voltage cables. In 1913, the German M. Hoch Stette developed the component phase shielded cable, which improved the distribution of electric field inside the cable and eliminated the tangential stress on the insulation surface, which became a milestone in the development of power cable. In 1952, Sweden installed 380 thousand volt ultrahigh voltage cables in the northern power plant to realize the application of ultra high voltage cables. By 80s, 1 million 100 thousand volts and 1 million 200 thousand volts of UHV electric power cables have been made.
