China Construction machinery information

Guide: Recently, the wiring work of the 500 kV Liantang Sijing transmission line of East China Power in the province (autonomous region and city) officially began. This line will be connected to UHV power, and will transmit more water and electricity to Shanghai due to the influence of green connection temperature on the microstructure and performance of TA2 titanium plate instantaneous liquid phase diffusion connection joint. It is estimated that in the next five years, the maximum power load of Shanghai power will exceed 37million kW, and the annual power consumption will exceed 1700

recently, the wiring work of East China power 500 kV Liantang Sijing transmission line officially began. This line will connect ultra-high voltage power and transmit more "Green Hydropower" to Shanghai

it is estimated that in the next five years, the maximum power load of Shanghai power will exceed 37 million KW, and the annual power consumption will exceed 170 billion kwh. In the future, with the construction of AC UHV Shanghai station and Suzhou station, the power handling capacity of Shanghai power will be significantly improved. By 2015, Shanghai UHV and 500kV power will be connected through four channels, and two 500kV power stations will go deep into the central urban area from the ring road. By then, nearly 30% of the electricity in Shanghai will be clean electricity delivered by UHV

according to the plan of the State Grid Corporation of China, East China power will form a UHV receiving ring from Shanghai, Jiangsu, Zhejiang and Anhui, and receive external power through four UHV channels. At the same time, the UHV frame extends southward, covering four provinces and one city of East China power. Therefore, the flow channel should be short. East China power company proposed that during the "12th Five Year Plan" period, the construction of a strong power structure in East China will be accelerated to deliver more high-quality "energy" for the economic and social development of East China. It is reported that by 2015, the scale of external electricity in the district will continue to increase, from 13.5 million kW in 2010 to 72.8 million KW, an increase of more than four times, accounting for 28.2% of the maximum power load

by the end of last year, the Xiangjiaba Shanghai ± 800 kV HVDC demonstration project independently researched, designed and constructed by China had operated safely and stably for nearly half a year, transmitting 5.891 billion kwh of electricity to East China and receiving 2.31 billion kwh of electricity in Shanghai. This demonstration project is a DC transmission project with high transmission control accuracy, the largest capacity, the longest transmission distance, the most advanced technology and the highest voltage level in the world. Its transmission capacity reaches 7million kW, and it can transmit 35billion kwh of clean Hydropower to Shanghai every year, equivalent to 30% of Shanghai's annual electricity consumption
