Core Viewpoint - The Hami to Chongqing ±800 kV UHVDC project is a significant infrastructure initiative aimed at transmitting clean energy from Xinjiang to central and western China, enhancing energy security and promoting green energy utilization [1][6]. Group 1: Project Overview - The Hami to Chongqing UHVDC project spans approximately 2,290 kilometers, connecting five provinces: Xinjiang, Gansu, Shaanxi, Sichuan, and Chongqing [1]. - The project is expected to deliver 36 billion kilowatt-hours of electricity annually, with over 18 billion kilowatt-hours sourced from wind and solar power, effectively replacing 6 million tons of coal and reducing carbon dioxide emissions by 16.5 million tons [2]. Group 2: Renewable Energy Contribution - The project boasts a record of over 70% renewable energy in its installed capacity, with 10.2 million kilowatts out of a total of 14.2 million kilowatts coming from wind, solar, and thermal sources [2]. - The natural time zone complementarity between Xinjiang and Chongqing allows for efficient energy supply during peak demand periods in Chongqing [2]. Group 3: Technological Innovations - The project employs advanced technologies such as the dual-arm support technology, enhancing wind resistance by 50% and doubling construction efficiency [3]. - The use of high-strength aluminum alloy components and a unique aerial transport system has significantly improved the project's logistics and construction timelines [3]. Group 4: Economic Impact - The Hami UHVDC project has an investment of 28.6 billion yuan, stimulating over 100 billion yuan in upstream and downstream investments and creating more than 40,000 jobs [5]. - The project has catalyzed the growth of a complete industrial chain in renewable energy equipment manufacturing, contributing to a 20 billion yuan increase in the value of the power transmission and transformation equipment manufacturing sector [5]. Group 5: Future Developments - Following the completion of the Hami to Chongqing project, plans are in place to accelerate the construction of additional UHVDC and AC transmission lines to further leverage Xinjiang's resource advantages [6].

哈密至重庆±800千伏特高压直流输电工程将于5月 建成投产 "我们采用无人机代替人工进行高空监理验收，一方面，无人机巡检大幅减少了人工投入，避免验收人 员在低温高空环境下遭遇危险，保障了工作人员的生命安全，也降低了人工成本支出；另一方面，无人 机验收大幅提升了验收效率，无人机能够快速穿梭于杆塔之间，在短时间内完成大面积的验收任务，相 较传统的监理人员登塔、走线验收，效率提升数倍，有效提升了监理初检验收的工作效率和工作质 量。"该工程总监黄平介绍。 在此次监理初检验收工作中，无人机团队负责对哈密至重庆±800千伏特高压直流输电线路工程甘8标 163基铁塔、97.61千米线路段进行巡检，顺利完成验收任务，发现并记录有关问题，为工程整改提供关 键依据。 据悉，哈密至重庆±800千伏特高压直流输电工程计划于5月建成投产。工程投产后，每年可从新疆向重 庆输送电量超360亿千瓦时，进一步推动新疆能源资源优势转化，促进其开发利用，对推动西部地区经 济社会的可持续发展意义重大。同时，服务全国保供大局，助力新型电力系统建设，为重庆经济社会发 展提供强有力的电力保障。 国网福建建设（咨询）公司工程监理部凭借敏锐的行业洞察力与专业 ...
