In order to guarantee high reliability of operation of overhead contract line equipment, on basis of analyzing the lightning protection measures for overhead contract line equipment in Germany and Japan, with reference of the statistical analysis of tripping of part of Datong-Xi'an high-speed rail line which is liable to frequent lightning strike, the paper puts forward a lightning protection proposal on reconstruction of overhead contract line equipment of Datong-Xi'an high-speed railway. According to the specific conditions, measurements are increased or decreased on basis of feasible technology, convenient construction, moderate investment, minor influence on train operation and reliable implementation of measures so as to achieve good lightning protection effect.
