In November 9th, the + 1 million 100 thousand volt Changji - paleospring HVDC transmission line project was connected to the 2 section. At this point, the line of Gansu, Gump 1, Gump 2 section 299 kilometer line demonstration section through.
- 1 million 100 thousand volt line sections west of Xinjiang Changji converter station, East Anhui Guquan station, passing through six provinces, with a total length of 3319.2 km. Which is located in the territory of Gansu, Gan Gan 1 2 section of 299 km line across the board is the demonstration, the construction management of DC network company, Sichuan electric transmission company, Qinghai electric transmission company, construction and management of high standards and strict requirements of construction, play a leading role in the whole sample of each section in the.
In May 20, 2016 the project started, State Grid DC company to standardized procedures and standardized construction as the basis, to the management and technical innovation as a means to mechanized construction process, site safety and engineering entity and nature as the goal, innovation, leading the demonstration, full line construction, solid the project to promote the orderly conduct of the work.
In the construction process, the national network of DC company owner project department give full play to the functions of the site construction management center, and urge all units to strictly implement the investment of resources and technology, site safety and quality control measures in advance judged, earnestly docking site management and coordination, construction safety and orderly. State Grid DC company focuses on the construction of intelligent + 1 million 100 thousand volts, relying on the two-dimensional code cloud disk project management technology, and establishes comprehensive data platform, integrates on-site personnel, machinery, equipment, materials, environment and other information data, and accurately controls the project site in the whole process. - 1 million 100 thousand volt line sections Gan 2 section construction process difficulty prominent, control is very challenging, Sichuan songbiandian Co. research foundation, Gobi construction group to tower, line "construction mechanization" whole process method, the successful implementation of the country for the first time more than 500 ton tonnage crane mobile crane group stands 110 meters tower. In the process of construction, the company has implemented the "plastic polymer waterproof template pouring the foundation" and "intelligent drop based maintenance device" and "construction" tower crane group "detachable crossing frame + suspension bridge insulation block technology innovation process, and built the" auspicious spring line boutique in the boutique "lay a solid on the basis of.
