About us

 

 

S.C.RETRASIB S.A. SIBIU is a company specialized in the manufacturing of equipments of the power grid and distribution.  

In 1895 was founded the HEV (Hermannstadter Electrizitat Werk- Electrica l Plant Sibiu) with Swiss capital, whose main activity was the production  of electrical energy. In 192 4 was founded an anonymous company named The Company of Electricity Transylvania, which mainly deals with the power grid and distribution in the south of Transylvania.  
 

 
 

 

For the internal needs of these companies and especially for HEV, between 1917 and 1945, there were built several workshops designed for repairing and maintenance ac ivities such as: carpentry, turnery, forging, welding and  winding, where there were repairing engines up to 5 kW and transformers up to 400 KVA. 
     
In 1948, after nationalization, by merging the two electric companies, results the Regional Electricity Company Sibiu (SRE). After 1948, SRE Sibiu continues its development process, at the same  time with the development and the expansion of the energy system. Starting with 1953 there were discussions about reorganizing the winding workshop, respectively about the modernization and the specific endowments in order to repair high power transformers. 
   
The activity of repairing during the years 1956-1957, the first power transformer of 20 MVA, 110/5,5 kV, came from VEM (Germania), was practically the beginning of the rehabilitations made by S.C. Retrasib S.A. This activity becomes permanent in 1958 when it was established the repairing hall for electrical machines and high power transformers, at the same time with the reorganization of the MEE entities and with its renaming in The Company of Electric Networks Sibiu (IRE).

If in 1957 had been repaired only a transformer of 20 MVA whose repairing lasted for almost a year, in 1976 there had been repairing 18 transformers with powers higher than 10 MVA, the duration of the repairing being shortened, in average, at 90 days. During 1960 - 1975, in IRE Sibiu’s workshops, there were repaired, for the energy system, almost 400 transformers with powers higher than 1 MVA. 

In parallel with the repairs, it also started the energy equipment manufacturing, such as: arc suppression coils, earthing transformers and coils, resistors for neutral treatment of electrical networks,  special transformers for tests, products needed for average and low voltage networks (clamps, fittings, brackets, caps, alcoves branching).   

In 1977 started the construction for a new production base meant to repair big transformers, nearby Sibiu Sud 400/220/110 kV station. The construction was finished in two stages, in 1982 and 1986 and it consisted of a repairing workshop for transformers from 1 MVA to 40 MVA, having a slide bridge of 80/20 tf, an untanking workshop for transformers up to 400 MVA, having a slide bridge of 320/80 tf, a vacuum drying workshop (autoclave of 400 cubic meters), a high voltage laboratory for electrical tests, a mechanic workshop, an oil workshop and a chemical laboratory for the dielectric oil analysis.  

 

 In April 1993, RETRASIB detaches from the Ministry of the Electrical Energy and started to make the first step towards becoming a commercial private company.

 Starting from 1999 S.C. RETRASIB S.A. is a private company. 

Surface : 30.000 sqm, access with trailer and railway.

Number of employees : 202.
