It has been issued that the necessity of Live line work for 765kV vertical double circuit six bundle conductors transmission line when the characteristics of transmission line, the composition of T/L and near the T/L circumstances etc. Others are considered. The Barehand method of UHV T/L is extremely dangerous work and especially it is directly related with lineman life so it is very dangerous. It should be performed several technology developments for live-line work on the UHV T/L, that should be considered such as the electrical influence on workers near the T/L, development of live-line facilities, guarantee of safety, the technical rules of live-line work, the safe method of live-line work and etc. In order to maintain the 765kV transmission lines safely by barehand work, first of all, we should know the analysis of electrical safety level test in live-line work at 765kV vertical double circuit six bundle conductors on the suspension string tower type.
