Compact Power Transmission Lines

In this paper, the possibility of increasing the transmission capacity of power transmission lines 35 to 220 is considered. The methods of phase convergence and splitting are considered as known methods for increasing the capacity of power transmission lines, The use of insulating cross-arms and spacer blocks mounted between the wires of different phases, allows to bring the phases of power transmission lines together, thereby reducing the longitudinal reactance of the line and increasing the transverse capacitance. Similarly, by splitting the wires, it is possible to get the same results. The studies were carried out on the basis of an analysis of the equations determining the parameters of power transmission lines. The use of insulating cross-arms and spacer blocks allows not only to increase the transmitted power, but also to reduce the dimensions of power transmission lines and the alienation of land under it, to reduce the environmental impact. Increasing the capacity of power transmission lines will reduce the electric power network, thereby increasing its reliability and manageability.
