    According to data released by the National Energy Administration, from January to March this year, China's power grid engineering investment completed 54 billion yuan, a year-on-year increase of 48%, and the capacity of new substation equipment of 220 kV and above was 57.
    66 million kVA, a year-on-year increase of 1351%; The length of new transmission lines of 220 kV and above was 8,717 km, a year-on-year increase of 4,863
    %.
    As the world's most advanced transmission technology, China's UHV construction projects are also accelerating
    .

    According to SMM historical data, the total bidding volume of the Zarut-Qingzhou ± 800 kV DC transmission project put into operation at the end of 2017 was 84042.
    8 tons, of which the tender volume of steel core aluminum stranded wire was about 83794.
    1 tons, and the aluminum alloy strand was 248.
    7 tons, with a total aluminum amount of 68122 tons
    .
    Referring to the data of historical engineering (based on the average of straight-line distance and highway distance), the average aluminum consumption per kilometer of UHV AC lines is 63.
    43 tons, and the average aluminum consumption per kilometer of UHV DC lines is 55.
    17 tons
    .

    That is to say, with the acceleration of China's UHV construction, the output of electrolytic aluminum and aluminum alloy is also accelerating
    .

    According to data from the National Bureau of Statistics, in March, China's electrolytic aluminum output was 3.
    276 million tons, an increase of 8.
    5% over the same period last year; From January to March, the output of electrolytic aluminum was 9.
    758 million tons, an increase of 8.
    8%
    over the same period last year.
    In March, aluminum output was 5.
    367 million tons, an increase of 17.
    6% over the same period last year; From January to March, the output was 13.
    887 million tons, an increase of 31.
    1%
    over the same period last year.
    In March, the output of aluminum alloy was 870,000 tons, an increase of 23.
    9% over the same period last year; From January to March, the output was 2.
    266 million tons, an increase of 38.
    6%
    over the same period last year.

    It is reported that the transmission cable of the UHV power grid project mainly uses steel core aluminum stranded wire, which is made of aluminum wire and steel wire twisted, of which aluminum stranded wire mainly plays the role of transmitting electric energy, under the premise of meeting the same conductivity, the length of the same quality aluminum alloy cable is twice that of copper cable
    .
    Data show that electrolytic aluminum used in China's power industry accounts for 13% of domestic consumption, and with the continuous advancement of UHV power grid projects, the proportion of electrolytic aluminum and other consumption will increase
    year by year.
