Abstract

A three-phase overhead electric line contains split phases (1, 2 and 3), wires (4) of which are mounted on metal spacers (5), those spacers forming, in a plane perpendicular to the axis of the electric line, countours of the cross-sections of the split phases (1, 2 and 3) fixed by means of insulators (7) to the electric line towers whose elements (8) are stretched beyond the space embraced by the split phases (1, 2 and 3) and by air gaps between them. The distances between the neighbouring split phases (1-2 and 2-3) of the electric line are, on the whole, constant throughout the length of their countours, whereas the wires (4) are so situated in the split phases that their charges and currents are close to their mean values, so that the electric field is weakly non-uniform throughout the entire volume of the interphase gaps, the electrical break-down being possible only in a striated form in the case of an overvoltage. The countours of the split phases may be of different configurations: closed, open and combined.
