Sae Power Lines


Technological innovation
From its origin SAE was conspicuous for its strong innovative charge, at the beginning due to the novelty of the business (the large projects in the transmission field) which required a continuous effort to find new reliable and effective solutions to make up for the limited experience and technical knowledge and then to maintain the market leadership, developing customer oriented solutions as well as to guarantee the best ratio quality vs. price.
Among the numerous innovations we can remember:

  • the introduction (1937) of the high strength steel quality in the design and manufacturing of low weight towers;
  • the automatizated “Tower Testing Station” in Lecco (Italy), where more than 3,000 prototypes of towers have been tested;
  • The automatic calculation (Elastic analysis) of the lattice towers using the electronic computer, developed during the years 1959-1961 with the “Battel Institute” of Genève (Switzerland);
  • The automatic design and optimization of the whole lattice towers including legs and extensions made in a single shot;
  • The introduction of the CNC machines and the complete computer controlled manufacturing activities performed in  SAE’s factories, based on the design and drawings data;
  • The design and realization of continuous hot-dip galvanization plants, introduced in the SAE’ factories;
  • The pile foundations used for Transmission lines;
  • The stringing operation by means of special tensioning equipments;
  • Stringing by helicopter;
  • Fully automatized CAD for manufacturing drawings of the steel members of towers;
  • Development of new “cold formed sections” particularly devoted to the structures optimization;
  • Automatic design and optimization of the line routing and tower spotting by means of special software using satellite data;

A particular care was taken by SAE when the need to safeguard the territory and the environment increased, this fact led SAE to search for alternatives to the conventional overhead lines.
Starting from its experience in HV power transmission lines, the com­pany has undertaken various studies and experimental programs resulting in Flexible Compact Transmission Lines, following engineering and erection criteria oriented towards both safeguarding the environment and reducing the visual impact in urban and suburban areas.
The result in terms of performance, reliability and costs competes favourably with that of the conventional lines.
The lower environmental impact is achieved essentially through:

  • replacing the structural elements with boxed elements (like tubular)
  • a smaller right of way and foundation area
  • reducing the height of the supporting elements and the size of their upper portions.
