The article presents the results of modeling of electromagnetic fields (EMF) created by a three-chain power line 110-220 kV. For comparison, the simulation of EMF of the transmission line corridor formed in parallel with the laid 110-220 kV air lines was performed. The simulation showed that the total electromagnetic the impact of the three-chain line on the environment is much lower than when laying the same power lines on separate supports.
