A thought about phase-phase distance of the pulled tower of thecompact transmission line

摘要

To the routine transmission line of 500kV, because of the metal tower between the two phases, the phase-phase distance do not play the leading role. The CSG company has successfully built and operated the fourth line of TianShengQiao-GuangZhou, a part of which is the compact line between LuoPing-BaiSe(LuoPing YunNan-BaiSe GuangXi) (FCL). We found that the phase-phase distance of the pulled tower can not fit the rules in our checking work, so it is a important factor to the safety of grid which we should control.
