Distribution Transformers
- These are transformers that can be used in distribution systems.
- It is used as step-down transformer in industrial facilities and collective settlement centers.
- It can be used as step-up transformer in power plants.
- It can be designed as Load or Idle Switch.
- Transformers can be mounted inside cabinets with IP55 protection degree.
- Production capacity is up to 40 MVA and 72.5 kV.
Earthing Transformers
- It provides fault current measurement by creating a neutral point in insulated systems and is used to protect the system.
- Transformers can be mounted inside cabinets with IP55 protection degree.
- Production capacity is up to 72.5 kV regardless of power.
Rectifier Transformers
- They are transformers used to provide rectifier units in different industrial areas.
- They are used for traction applications in metro and tram lines, marine propulsion systems, warning functions in power plants and industrial motor-converter systems.
- It is produced in 6, 12 and 24 pulses.
- Transformers can be mounted inside cabinets with IP55 protection degree.
- Production capacity is up to 20 MVA 72.5 kV.
Shunt Reactors
These special transformers are used for compensating capacitive load formed in power transmission lines at times of low load. Therefore, they are rated according to their reactive powers.
They increase energy quality and efficiency of the grid by preventing over voltages besides their duty of compensation.
- Production capacity is up to 10MVAr, 72,5kV.
- Acts as inductive load on high voltage transmission lines.
