THE RIGHT WAY FOR FITTING SYSTEMS
Salvi is a Company highly specialized in the design, manufacturing and testing of hardware and fittings for high and extra high voltage overhead transmission lines and for railway electrification. Established in Milan in 1920, in 2002 the Company joined the Sicame group, an international group fully operative with 52 Companies operating in 24 countries, selling over 150 countries worldwide. Thanks to the technical, manufacturing and commercial evolution, as well as the international expansion strategy, the Company has been specialized in the field of the hardware and fittings for overhead transmission lines from 33 kV up to 800 kV, in the context of which Salvi is recognized with a very important key role. Thanks to almost a century of history and activity in a such specific scope, Salvi has achieved a unique experience worldwide, symbol of the Italian excellence in the research, manufacturing and realization of high profile products.
Safety, fundamental principle in the field of electricity transmission lines, has always been the Company main objective, for both products and offered services. In this respect, hardware, accessories and damping system are as important as the towers, the conductors and the insulators.
Salvi offers, for the full range of products, absolute reliability, flexibility and versatility, as well as the study of innovative and creative solutions to any problem. The Company is also specialized in the design and execution of high technological projects, requiring a highly qualified internal organization, a proper laboratory and a close cooperation with the Research Institutes and Universities. In particular, Salvi excellence areas are the damping of vibration on cables for special structures, hardware for long crossing spans, the special components, the torsional absorbers that control the sub-span oscillations on quad bundle conductor lines and the spacers for expanded bundle conductors up to 1.200 mm.
The production capacity exceeds 5.000 ton/year of hardware and damping system (up to 240.000 twin, three, quad and six bundle spacer dampers and up to 140.000 vibration dampers) and accessories, reflecting around 5.000 Km transmission lines from 132 kV up to 400 kV.
HISTORY OF THE COMPANY
The Company was established in Milan in 1920 as private company by Alessandro Salvi, businessman and owner of an import – export company in the hardware field, which imports in Italy from the American Company Ohio Brass, which has been incorporated nowadays in the group Hubbell. The decision to start up an own production line has been taken as recommended by private electrical power grids which dominate the Italian market in the early 20th century, of which Salvi is a privileged partner: among the most noteworthy the Sip (Società Idroelettrica Piemontese) in Turin, the Sade (Società Adriatica di Elettricità) in Venice and the Sedac (Società Elettrica della Campania) in Naples.

If the major part of the Company turnover comes from the manufacturing of fittings, in the middle of the last century Salvi distinguishes itself for its high engineering capacities in the field of the electrical crossing of valleys, lakes and rivers.

So, a long specialization process starts, taking Salvi to implement and record over 500 electrical type tests, an experience representing great strength and distinction from the competitors. Among the most important crossing for long span executed by the Company all over the world, there are the crossing of the Strait of Messina in 1968, on the river Danubio in the then Yugoslavia in 1970, in Arkansas in U.S.A. in 1971, in Schelde in Belgium in 1973, on the Pearl River and Yang-Tse, both in China, in 1986, in the river Orinoco and lake Maracaibo in Venezuela, respectively in 1990 and 1997, in the Niger Delta in 2003 in Nigeria.
In addition to the long crossing span, Salvi is specialized also in the manufacturing of special vibration dampers for special structures, as the panoramic wheel in London (London Eye), built in 2000 with an overall length of 135 meters. Furthermore, the Dubai wheel (Dubai Eye), with a length of 210 meters aspires to be the highest in the world, and the New York wheel (192 meters): both will be completed in the next years. Among the major works that have been implemented by Salvi there are the Braga stadium in Portugal (2003), the Humber Bridge (2004) and the new Wembley stadium (2005), both in the U.K. and the Benetton factory in Italy (2009).
Salvi expertise and experience enriched over time also thanks to the agreement with the Department of Mechanical Engineering of Politecnico di Milano, launched in 1966 and still ongoing. In the “wind tunnel”, that originally was located in Via Cosenz and is now inside the university building, the electrical elements are being tested to withstand a force of 300 Km hourly. An agreement that has given rise to a pole of excellence in the solution of the vibration phenomena in the high voltage overhead transmission lines. From these studies a new idea was born: the asymmetric spacer damper that, at the same performances conditions of a standard four bundle spacer damper, allows the reduction of the needed number of spacer damper for each span.
In 2002 Salvi has been incorporated at 100% into Sicame, an international group of French origin which comprises 52 Companies operating in 24 countries, selling over 150 countries worldwide.
Salvi is part of the Transmission SBU (Strategic Business Unit), along with other 4 foreign companies (located in France, India, Brazil and Canada).
Salvi main reference markets are Italy, Europe, North America (Canada and Unites States), Saudi Arabia and the other Gulf countries.
