The compact power transmission technology is a new technology which is developed quickly and applied in China for recent years.Compared with conventional lines,the compact power transmission lines improve the deliver-y of natural power,compress the width of corridor,and have lower construction cost.This technology has great e-conomic and social benefits.To ensure the safety of live working on 750 kV compact power transmission lines-we focused on the safety protection,put forward the method and entryway of live working,and calculated the danger- ous rate.The results show that the horizontal channel is the best entryway of live working.
