Xinjiang 750kV UHV transmission lines is an important part of the advantageous resource transformationstrategy in Xinjiang. In the energy strategic layout

it can help realize power mutual supply between North and Southof Xinjiang

between hydropower and photovoltaic power. Meanwhile it can improve power supply reliability and thecapacities of mutual supply and accepting the new energy capacity.Xinjiang 750kV UHV transmission lines coverslarge regions. The regions’ terrain along the lines is complex. The strong wind is the meteorological characteristic andone of major external factors leading to lines’ faults. The operation and maintenance of 750kV lines need masteringthe spatial and temporal characteristics

so as to carry out the special treatment. Based on the terrain DEM data andthe data of wind speed and direction from 2011 to 2015

this paper analyzes data of the terrain and wind conditionsalong 750kV UHV Transmission Lines in Xinjiang

such as poles’ altitude

slope

aspect

annual average windstrength

over 6 level wind and so on. The conclusions give the concrete values

which reflect the global temporal andspatial characteristic of Xinjiang 750kV UHV transmission lines

and provides the key basis for the special prevention and treatment of wind damage and improving the commercial efficiency of design and build.
