Tower, particularly for a high-voltage overhead electric transmission line, equipped with switchgear unit and related protection, command and control system

A tower for a high-voltage overhead electric transmission line,

• wherein said tower has a predetermined shape defining an internal volume of said tower, and carries a first tension side of a first line section and a second tension side of a second line section, wherein said first tension side and said second tension side comprise respective pluralities of first and second phase tension terminals each associated with a respective phase of the high-voltage overhead electric transmission line;
• said tower being configured to support, within said internal volume, a switchgear unit connected at a first end to said first line section and at a second end to said second line section;
• said switchgear unit, being configured to modify a grid configuration, interrupting and restoring electrical continuity at predetermined points, interrupt nominal and fault currents, and carry out safety operations, through grounding, of the first or second line section;
• the switchgear unit comprising a plurality of switchgear unit poles, each switchgear unit pole of said plurality of switchgear unit poles being associated with the respective phase of the high-voltage overhead electric transmission line;
• and
• each switchgear unit pole comprising a line circuit breaker and at least one line disconnector.
