With global climate changed

extreme weather with rain and snow appears much more frequently in China

and the galloping of transmission lines which is easy to tend to evoke the nasty accident of inter-phase short-circuiting

conductor burned

hold down towers

and conductor broken appears frequently too

which cause huge economic loss.Thus

the study and divide of the high voltage overhead transmission lines’ galloping region appears particularly important.Members of the research group made a field survey on the whole 1 000 kV lines

and gathered a lot of meteorology date of the line through areas.We divide the galloping region of this 1 000 kV line

based on the analysis of the basic theory of galloping region and combined with the topography and meteorological conditions of area which line across

wants to provide some help and guidance to the operating unit to carry out more efficient operation and maintenance management.
