2. Extending the lifetime of a transformer on site
A large number of transformers in operation has already exceeded the technical lifetime assumed by the constructor. However, in most cases, the actual technical condition of the active part of these units is very good. By performing renovation and modernization procedures, it is possible to extend the time of their safe operation without incurring much higher costs related to the need to purchase a new unit.
The main motto of the company is: “Transformers – comprehensive solutions”
The first stage of such operation is performing a full diagnostic of the unit and assessing the cost-effectiveness of planned renovation or modernization. Depending on the current technical condition of the unit, it is possible to carry out the following works: revision of the active part, replacement of equipment including bushings, replacement or repair of the cooling system, renewal of paint coatings, sealing and liquidation of leaks. In addition, it is possible to carry out service (major overhaul) or replacement of the on-load tap-changer (OLTC) on-site.
