1. A lattice tower (40) for a high-voltage overhead transmission line (60, 90), the lattice tower (40) having a lattice structure comprising:
a base (41) anchored to a ground;
a top portion (43) designed for anchoring first conductors (51) and second conductors (52) of the high-voltage overhead transmission line; and
a body (42) which extends between the base (41) and the top portion (43);
wherein
a lattice tower comprises a grid high-voltage electric switching substation that includes: GIS-technology-based switchgear equipment (401);
a first loop-in loop-out feeder connection (402) that is configured to connect the first conductors (51) of the high-voltage overhead transmission line to the GIS-technology-based switchgear equipment (401), and made by insulated cables or GIS-technology-based ducts, or by mixed solutions wherein a first portion is made by bare conductors and a second portion is made by the insulated cables or the GIS-technology-based ducts;
a second loop-in loop-out feeder connection (403) that is configured to connect the second conductors (52) of the high-voltage overhead transmission line to the GIS-technology-based switchgear equipment (401), and made by insulated cables or GIS-technology-based ducts, or by mixed solutions wherein a first portion is made by bare conductors and a second portion is made by the insulated cables or the GIS-technology-based ducts; and
a protection, command and control system (405) arranged within the lattice structure (40), or in proximity to the base (41) of said lattice structure;
wherein the GIS-technology-based switchgear equipment (401) is designed to be connected also to a user connection line (407);
characterized in that the GIS-technology-based switchgear equipment (401) is arranged within the base (41) of the lattice structure.
