1. A high-voltage overhead electric transmission line, which extends from a first electrical substation to a second electrical substation, wherein the high-voltage overhead electric transmission line comprises at least one “T” junction that forms a three-section joint, wherein a first section and a second section are configured to allow electric connection between the first electrical substation and the second electrical substation, and a third section is configured to allow an electric connection between the high-voltage overhead electric transmission line and an entity selected from a group consisting of a user, a primary station, and a third electrical substation, wherein the at least one “T” junction comprises two switchgear units: a first switchgear unit configured to allow grid reconfigurations and installed on the first section, and a second switchgear unit configured to allow grid reconfigurations and installed on the second section;
each switchgear unit comprising a plurality of switchgear unit poles, each switchgear unit pole of said plurality of switchgear unit poles being associated with a respective phase of the high- voltage overhead electric transmission line; and
each of said switchgear unit poles comprising a line circuit breaker and at least one line disconnector.
