Milano, June 17, 1926. Company managers, lawyers and a notary met in Foro
Bonaparte to set up a new electrification company: SAE (Societ Anonima
Elettrificazione), to electrify the Bolzano-Brennero railway line. It was the first
electrified line in Italy
Despite the original agreement providing for the windup of the company once
the project had been completed, SAE was awarded other projects and expanded its
activities in Italy and abroad

Over 135,000 kilometers of experience in the power transmission and distribution field in Italy and all over the world. A leadership lasting since 1926 is a reference of absolute distinction.
The story of SAE begins in 1926, with the
electrification of the double-track Bolzano- Brennero
railway line in Italy. In the following years, the
company extended its activities, particularly in the
power transmission field, acquiring the expertise
enabling it to become a worldwide leader in this
sector.
SAEs mission, evidenced by 135,000 kilometers of lines built in Italy and abroad (i.e.
enough to go round the world more than three times),
is to guarantee the power transmission and
distribution with the best technical, economic and
environmental parameters and with the utmost
reliability.

Our technological resources combined with our people's exceptional expertise and experience enable us to deal with all kinds of OHTL projects.
Implementation capabilities.
In Italy, the company has given a substantial
contribution to the country's energy transmission
development, building many 380 kV transmission
lines for ENEL, as well as introducing innovative
solutions such as the experimental 1,050 kV
transmission line in Toscana and the compact 132
kV transmission lines with a low environmental
impact.
Overseas, working with utilities in various
countries, the company built lines ranging from 11
to 800 kV and has acquired a wide experience in
dealing with extra-HV lines ranging from 380,
400, 500 kV, up to the 765 kV lines built in South
Africa.
EHV Direct Current lines where built since
1976 starting from the 1,400 km Cahora Bassa
(Mozambique) at 533 kV, up to the Greece-Italy
interconnection 110 km at 400 kV completed in
2002.
A complete power transmission system.
SAE is capable of supplying a complete power
transmission system and the relevant distribution
networks. In addition to the primary HV/EHV overhead
transmission lines which are the core business of the
company, SAE also designs and builds

Protection, Control and Signaling
Panels (PCM) and Distributed Control
Systems (DCS).
The role of SAE.
With over 80 years of experience,
SAE acts as General Contractor, taking
the leading role in consortia and joint
ventures, especially for turnkey EPC
projects, developing and managing all
activities, from the feasibility studies to
the commissioning of the plant.
A flexible structure, always adaptable to the customer needs.
The establishment of local branches
all over the world enables SAE to use a
flexible organization, capable of
utilizing and managing local resources
and tailoring the product to the
customer needs. This approach allows
to operate in different countries
respecting the local culture, people and
environment
From the feasibility study to the commissioning, here's what we are able to do.
TRANSMISSION SYSTEM ENGINEERING - transmission lines design - routing optimization and tower spotting - AIS substations design
STRUCTURAL ENGINEERING - towers for high and medium voltage lines - catenary poles and portals
CIVIL ENGINEERING
- geological surveys
- foundations
- auxiliary buildings
CONSTRUCTION - topography - material supply - civil works
- erection and stringing of transmission lines - test and final inspections

Executing all kind of projects, whatever the environmental conditions, from engineering to commissioning, to subsequent technical assistance, with virtually no limits in our service activities
A team work to overcome all difficulties.
SAE often has to deal with problems of
considerable complexity of technical, management and
environmental nature.
As an example, a particular project that the
company had to cope with, was the 230 kV dc
transmission line crossing the Strait of Gheshm in Iran,
the only case in the world of a crossing tower with a
prefabricated offshore foundation placed in the sea
having the size of a civil building (30 x 30 x 21 m) and
weighing 6,000 ton.
or the 500 kV dc transmission line in China, crossing the Pearl River with one of the tallest towers
238 meters over a 1,547 meters span.
The quality
To manage complex projects, it is essential to
ensure the utmost integration of resources and
coordination of company functions.
In order to be able to
guarantee all phases of its
work, the company installed a
quality system obtaining the
certification, from the
Norwegian Det Norske
Veritas standard, that complies
with the UNI EN ISO 9001
certification.
... for a job done safely.
We always focus on the personal safety: conditions
of the utmost safety must be guaranteed during the
construction stages, where the work could become
dangerous due to energized elements or due to the
complexity of the construction activities.
That is why an accident prevention and job safety
program has been developed with specific "Operating
Instructions" for each phase of the work execution.

Technological innovation
The increasing needs to safeguard the territory and
the environment led SAE to research 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
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 compare favorably 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 - restricting the height of the supporting
elements and the size of their upper portions
