Power Plants, Factories, Malls, HV-LV Substation Periodical Maintenance
Electricity Generation and Distribution Facilities, Factories, AVM and 154 kV - 380 kV Transformer Centers; We are able to perform periodic preventive maintenance of the facilities with our experienced cadres. The main purpose is; Maintenance / repair / parts replacement of equipment, especially those directly affecting production facilities, in pre-determined times to reduce the frequency of failure.
'Periodic / Planned Care and Rehabilitation Aims;
- Quality, safe and continuous energy production
- Increase the efficiency of the facility and substation to the highest level
- Reduce production costs
- Reduce unexpected failures
- Minimize the use of unnecessary materials
- Minimize unwanted events, trip and unplanned loads, etc
- Prevent premature failures by pre-detecting faults
These main criteria are the factors directly affecting the performance of the facilities and substations.
