The SAVET staff of experts has over decades of know-how in the field of design, construction and reconstruction of High Voltage Power Stations, High Voltage and Medium Voltage primary stations and general work on this type of installation.

As the subject matter is extremely complex and requires various types of expertise, below is a short summary, of the main work methods used.

In particular, to carry out this type of work, the company adopts the work procedure briefly described and schematized below.

Construction/reconstruction of power stations and primary stations – regulations and technical specifications applied by our company for this work.
