Electricity.Next year, British Ka Lunde inventions bituminizing paper insulation power cable.1889, British S.Z. Ferranti, Sebastian Ziani des were in London
10 kilovolts of oil-impregnated paper insulation cables have been laid between moral spy Ford.1908, Britain built up 20 kv cable nets.Power cable
Obtain increasingly wider application.1911, Germany's laying started the development of high-tension cable into 60 kilovolts of high-tension cables.1913
Year, German M. Huo Xishitaite are developed into individually screened cable, improve the distribution of cable internal electric field, eliminate insulating surface
Positive shearing stress, become the developing milestone of power cable.Nineteen fifty-two, Sweden have laid 380 kilovolts in northern power plant and have surpassed
High-tension cable realizes the application of extra-high-tension cable.1100 kilovolts, 1200 kilovolts of extra-high voltage electric power electricity has been made to the eighties
Cable.
