VOLTAK's Range of Distribution Transformers: Delivering Power with Precision and Efficiency

Oil Type Distribution Transformers

VOLTAK supplies oil type distribution transformers, which can handle input and output voltages up to 36 kV with a capacity of up to 5000 kVa. These transformers use transformer oil for cooling and come in two main types:

Hermetic Oil Type Distribution Transformers: These transformers range from 25 - 5000 kVA and up to 36 kV voltage level. They are hermetically sealed to balance oil pressure and prevent contact with the atmosphere, ensuring efficient operation and long life. Their compact design makes them suitable for smaller spaces, and they don’t require frequent oil changes.

Transformers with Conservator Tank: Similar to hermetic transformers in structure, but with conservator tanks designed to store excess oil. These transformers are open to the atmosphere, making regular maintenance such as silica gel replacement and oil sampling necessary.

Dry Type Transformers

These transformers differ from oil type in their cooling method. VOLTAK supplies dry type transformers with high voltage windings coated in epoxy cast resin. They are available in natural air cooled (AN) or fan cooled (AF) variants, ranging from 25-25000 kVA and up to 36 kV voltage level. Fan cooling can enhance their power by up to 40%. These transformers are increasingly popular due to their environmental safety and reduced fire risk.

Special Distribution Transformers

VOLTAK offers specialized transformers for specific applications:

Inverter Transformers-Converter: Used in various systems like VFD and VSD drives, solar and wind systems, they can be produced as dry or oil type, with different cooling options.

Other Special Type Transformers: Including Isolation Transformers, Crane Transformers, Test lab Transformers, and more, designed for specific industrial needs.

Grounding Transformers

Used to create a neutral point in three-phase systems lacking one. These transformers, which can have different connection structures like zigzag or star-delta, are essential for grounding isolated systems.

MT Shunt Reactors
These reactors are available from 25 kVAr - 10 MVAr, up to 36 kV, in various types like three-phase or single-phase, oil or dry type. They are essential for maintaining the power balance in capacitive operations.

Magnetic Control Shunt Reactors
Ranging from 1 to 10 MVAr and up to 36 kV, these oil-type reactors are compact and easy to install. They are key in improving the reactive power balance, enhancing the efficiency and stability of electrical systems.
