Repair of transformers
Development of design and technological documentation, technical guidance and performance by specialistsof SEC "ZTZ-Service" of preventive and remedial repairs, as well as a set of measures to extend the service life
Details
Diagnostics of transformers
Assessment of equipment serviceability, determination of the type, cause and danger of the defect.
Details
Installation of transformers
Technical guidance for installation and commissioning of transformer equipment of all voltage classes
Details
Transformer oil testing
After testing a sample of transformer oil in our laboratory, we answer the main questions about the condition of the transformer.
DetailsExtending the life of a transformer
Almost 25% of power transformers installed in the former USSR countries have reached the standard service life of 25 years or are approaching it.
To renew and extend the service life of a transformer SEC "ZTZ-Service" performs
- Inspection of the technical condition of a transformer, assessment of physical and moral wear of the structure
- Restoration of the mechanical state of a transformer
- Restoration of electrical strength by drying, cleaning, special regeneration, as well as reconstruction
- Reducing the rate of further aging by sealing, improving cooling, ensuring the durability of the oil
- Introduction of effective protection against damage, prevention of explosion and fire
- A set of preliminary, intermediate tests with functional testing of equipment
- Full technical support of further operation of a transformer
Development
SEC "ZTZ-Service" developed
Guiding documents for transportation, storage, installation and commissioning of 110-750 kV transformers
Technical requirements for technological equipment for oil treatment and insulation
Insulation drying technologies and protection against moisture
Process
Full cycle of works
Archival and electronic documentation is stored and analyzed for each of the transformers. In addition, SEC "ZTZ-Service" is the owner of archival and electronic documentation of more than 2,000 repairs of powerful power transformers and reactors manufactured since 1965.
Planning
Identify effective methods, techniques and resources needed to perform service tasks
Development
We prepare design, technological and software documentation
Implementation
We perform work with the maximum quality and reliability
Quality
Top quality on the market
The basis of the SEC "Service" work is the development of scientific and production base, active participation in the work of authoritative international organizations in the field of energy (CIGRE, DOBLE committees, TRAVEK), development of new methods and technologies, constant development and improvement.
