　　On January 20, in fujian province ningde tiger bei jiao city township MeiHe village - 1000 kv in the north of fujian province fuzhou uhv project bid section 16 of the "no man's land" construction site, the noise of the helicopters broke the silence of the mountains, its Chinese fujian electric power co., LTD., is using the helicopter on a large scale material lifting tower, this is the first time the nate high voltage engineering construction mass transport aircraft materials.
　　This the helicopter for KA - 32 a11bc type, the models had perform polar lifting tasks of the goods "snow dragon", the unit to perform a flight mission is ever executed "snow dragon" the task of lifting unit.The day lifting tasks from apron to bid 16 # A25 DaWei lifting material, number A25 DaWei position of ridge slope is more than 70 degrees, the plane eight long 10 meters of the lifting heavy 4 tons of steel, more accurate unloading location specified in the ACTS of the slope, and ensure that don't fall, challenge the limit of the flight.Helicopters from the apron take-off to DaWei placed material linear distance is about 5.28 kilometers, each material lifting and parked vehicles time, about 15 minutes each time can be an average of 3.5 tons, lifting material 14 tons per hour can be lifting materials, 20 times higher than that of ordinary transport efficiency.The helicopter will be completed within 30 working days, the north - fuzhou uhv engineering bid 16 "no man's land" 10 base tower tower weighing 2404 tons, base material and construction tools of transport task.
　　- fuzhou according to introducing, in the north of the uhv project is China's first large-scale construction project, the project connected in zhejiang and fujian provinces, is fujian province to realize large capacity across the province network of major projects, is fujian power grid voltage levels from 500 kv to 1000 kv across the upgrade of important symbol.Project 18 million kva substation capacity, the new middle of zhejiang, and southern of fuzhou transformer substation, substation, expansion in the north of the new line 2 x 603 km (2 x 428 km in zhejiang, fujian in 2 x 175 km), will be fully completed in December 2014.The complex terrain, weather, and changeful, the environment is bad.
If the conventional lines of 500 kv ehv is national highway, 1 million v high voltage line is the highway.North - fuzhou, after the completion of the uhv project is equivalent to build five 500 kv transmission line, the recent transmission capacity will reach 6.8 million kilowatts, the forward transmission capacity can be further increased to 10.5 million kw or more, to realize the transmission distance, large capacity, fujian's clean energy through the power "highway", more efficient, fast to east China, northwest, southwest of clean energy can also be sent to fujian to achieve "electricity come from far, coal for electricity generation, electricity generation oil", in order to reduce building coal-fired power plants in densely populated and economically developed area of middle brought about by the pollution of the environment, is of great significance to energy conservation and emissions reduction, deal with haze weather.At the same time, five lines of 500 kv ehv corridor width of at least 300 meters, and a line corridors of uhv line width is about 100 metres, can greatly reduce deforestation and the utilization of land resources, to achieve "green environmental protection, resource saving".
　　North - fuzhou uhv engineering bid 16 by company, installation of electricity transmission &transformation facilities of fujian province is one of the largest block construction in fujian, pouring concrete foundation 36975 cubic meters, raw material planning groups made tower 29780 tons, including single-base tower 117.7 meters, the highest most of 254.6 tons.This road is the blocks about 97% of the DaWei in slope steep hill or mountain ridge, lines 9 km route "no man's land", the mountainous mountains, cliffs, and human beings, to set up 44 of the average weight of 165 tons of steel tower, the Eiffel Tower, even more than the total weight of the French, plus local complex terrain, homework is very difficult.
　　"Option in the" no man's land "erect uhv line, although the construction difficulty bigger, but can avoid the construction in the densely populated area, reduce the cultivated land and resources, reduce the impact on the environment."When Lin said, assistant director of the priorities of fujian electric power infrastructure.
　　No can make use of the roadway near the "no man's land", build transport road, exist journey far, steep terrain adverse factors, material transport became "obstacle" of engineering construction.- fuzhou uhv engineering "in the north of 44 DaWei of material transportation," no man's land "is" no man's land "foundation construction progress of the key factors.", according to the deputy project manager Chen Jindong for up to 15 meters of the main steel and single 11.5 meters long and weighs 1.5 tons of materials, by artificial, horse on a cliff handling is entirely unworkable.
　　- fuzhou to solve in the north of the uhv project "no man's land" actual material transportation, promote the helicopter in the application of uhv transmission line construction, promote mechanization of our country's power grid construction and equipment level, decided to bid on the "no man's land" the implementation of a helicopter transport construction materials testing, not only effectively resolve the "no man's land" material transport problems, and through experiment further verify the helicopter in a particular area uhv project construction feasibility of large-scale material transport, other uhv engineering in our country for the next step in expanding application range.
The helicopter transport material first flight successfully, not only marks the level of fujian power grid construction to a new height, is also reduced by building construction road cut down trees and vegetation destruction, for building a green ecological engineering and has contributed to building a harmonious society.
