In the power sector, the reliability of equipment is not only a technical issue. It directly affects power supply continuity, plant safety, system efficiency and long-term investment stability. This is precisely why service, overhaul, revision and testing of transformers represent one of the key points in the life cycle of the power infrastructure.
In this context, Navitas DOO Belgrade , a member of XE Group , is developing a specialized branch Navitas TEX – Transformer EXcellence hub .
Navitas TEX is designed as an expert service center for assembly, overhaul, service, revision and testing of energy and distribution transformers in the field, as well as for assembly and servicing of equipment in high and medium voltage transformer stations.
Why is Navitas TEX important to the market?
Transformers are one of the most important components of the power system. Their reliability determines the safety of operation of transmission and distribution networks, industrial systems, facilities of renewable energy sources and large infrastructure facilities.
Any downtime, breakdown or inadequate maintenance can produce significant technical, financial and operational consequences. That is why the market is increasingly looking for service partners who can provide quick response, professional diagnostics, quality work execution and reliable technical support in the field.
Navitas TEX was created precisely as a response to these needs. Its role is to provide partners with an organized, professional and operationally efficient service capacity that can respond to the demands of the modern power sector.
What does Navitas TEX work include?
The primary activity of Navitas TEX includes the complete assembly of energy transformers at the user's location. This includes receiving and inspecting the equipment, mounting conductive insulators, cooling installations and protective equipment, vacuuming the transformer tank, oil filling, processing the insulation system, electrical and functional testing and putting the transformer into operation.
In addition to installation, Navitas TEX provides transformer overhaul services directly in the field. Such an approach enables works to be planned and implemented with minimal plant downtime, which is especially important for power transmission, power distribution, industrial and energy systems in which continuity of work is of high value.
Overhaul can include diagnostics of the condition of the transformer, revision of the active part, replacement of insulation components, service of the cooling system, replacement or regeneration of oil, thermal imaging and electrical tests, as well as putting the equipment back into operation.
Expertise for high power transformers
Navitas TEX has the capacity to work on transformers of various powers, from distribution units to large power transformers of up to 400 MVA , with a special focus on transformers of voltage level 110 kV and above .
This type of expertise requires a high level of technical knowledge, field experience, appropriate equipment and precise risk management. That is why Navitas TEX gathers a team of engineers and technicians specialized in working with high power electrical equipment.
The special value of this model is that the service team can provide support through various phases of the life cycle of the transformer: from assembly and commissioning, through preventive maintenance, to overhaul, revision and interventions in case of technical problems.
OLTC system service
An important segment of Navitas TEX's work is related to service and overhaul of load voltage regulators, known as On Load Tap Changer - OLTC systems.
OLTC systems play a key role in voltage regulation during transformer operation. Their correct functioning is of particular importance for the stability and quality of the power supply.
OLTC system service includes mechanism disassembly and inspection, contact replacement, drive mechanism adjustment, oil change, functional testing and commissioning. The works are performed in accordance with the manufacturer's requirements and the relevant electrical power standards.
Support to transformer stations
In addition to transformers, Navitas TEX provides maintenance and revision services for equipment in high and medium voltage transformer stations.
Services include inspection of medium-voltage installations, service of switches and disconnectors, control of protective systems, earthing measurements, control of cable connections and functional tests.
In the case of distribution transformer stations up to 35 kV and power up to 12.5 MVA, such activities contribute to greater operational reliability, reducing the risk of interruptions and extending the life of the equipment.
Technical capacity and quick response
One of the key advantages of Navitas TEX is the combination of professional staff, specialized equipment and the ability to quickly mobilize in the field.
The team has tools, instruments, spare parts and equipment for preventive and interventional maintenance of transformers, including modern solutions for drying and regeneration of transformer oil and insulation system.
This means that partners who need this kind of service can expect faster service delivery, reliable technical support and greater safety in the operation of their power plants.
Strategic partnership with ASTOR Enerji
Strategic partnership with ASTOR Enerji , a manufacturer of distribution, energy and special transformers, is of special importance in the development of Navitas TEX.
Through this cooperation, Navitas TEX additionally strengthens its capacities for defecting, assembly, service, overhaul and testing of transformers for the markets of Serbia, Montenegro, the Balkan region and the wider European area.
At the same time, Navitas TEX offers its services to other partners, manufacturers, OEM and EPC companies in the field of power engineering.
A reliable partner for the power sector
The development of Navitas TEX represents an important step in further strengthening the technical and service capacities of Navitas and XE Group in the field of electric power infrastructure.
For partners from the transmission and distribution system, industry, renewable energy sources, EPC sector and infrastructure projects, Navitas TEX brings added value through expertise, speed of response, technical precision and long-term reliability.
At a time when power systems require ever greater stability, efficiency and readiness for intervention, specialized service centers like Navitas TEX play an increasingly important role. Navitas TEX - Transformer EXcellence hub therefore represents a new professional address for all partners who need quality service, reliable technical support and safe operation of transformers and power plants.
