Abstract For 500kV vertically aligned compacttypetransmission linestowers,theairgapdischarge characteristicsare very different withtraditional compact lines, therefore, it is necessary to check its air gap distancebytest.In this paper, firstly, basis for the preliminary design of 500kVvertically aligned compact tower head is analyzed, and then, on simulation tower head, test research ofimpulse discharge characteristics and switching impulse discharge for live working is carried out. Results show that theair gap distance of 500kV vertically aligned compacttype transmission linestowers, which is selected according to traditional compact lines insulation coordination principle, is reliable. At last, the paper recommended the live working minimum safety distance of head to cross arm and head to the aboveconductor. Results can supply reference for the design and ensure the safety of live working of relevant personnel.
