TRANSFORMERS

Transformers are electrical machines that transform current and voltage values ​​without changing the power and frequency values ​​of electricity. In this way, energy losses are minimized and efficient operation is ensured at the desired current and voltage level. Our company supplies transformers in the 25 KVA-5 MVA power and 1-36KV voltage range. Our company operates in two main groups, oil type and dry type transformers.

Oil Type Distribution Transformers

Oil-type distribution transformers use mineral oil for cooling and insulation. These transformers are widely preferred in large-scale energy distribution networks and have the following features:

Hermetic Type Transformers: Hermetic oil type distribution transformers are manufactured by filling oil under vacuum, balancing the oil pressure and atmospheric pressure at the desired temperature, and ensuring that the cooling oil does not come into contact with the atmosphere. In hermetic oil type distribution transformers, internal heat as a result of changing oil pressure due to thermal changes is controlled by the natural expansion and contraction of the boiler wave walls. Mechanical design and manufacturing are done to withstand these effects. Hermetic oil type distribution transformers have lower heights than transformers with expansion tanks. Therefore, it can be used in smaller areas. Since the oil in hermetic transformers does not come into contact with the atmosphere, it does not require oil changes at certain periods, as in transformers with expansion tanks.

Transformers with Expansion Tank: Transformers with expansion tanks are the same as hermetic transformers with their core and coil structure. The dimensions of expansion tanks of transformers are designed as a result of calculations to store the expansion of oil that increases with temperature. Since transformers with expansion tanks are open to the atmosphere, the oil pressure changing due to thermal effects is dehumidified by the slicagel (air dryer) in the transformer tank and air exchange is ensured. As a result of air exchange caused by temperature differences depending on the load, the transformer with expansion tank that is put into operation loses its slicagel feature over time and causes the oil to become moist and its structure to deteriorate. For this reason, it needs maintenance such as changing the silicagel at certain periods and measuring the breakdown voltage by taking samples from the oil.

Dry Type Distribution Transformers

Dry type distribution transformers use air or solid insulating materials for cooling and insulation. These transformers have some distinct advantages over oil type transformers and are generally preferred in the following cases:

Lower Fire Risk: Dry type transformers are safer in terms of fire risk. Since there are no flammable liquids inside, the risk of fire is minimized. This feature provides a significant advantage, especially in areas requiring high security.

Eco-Friendly: These transformers stand out as an eco-friendly option. Since there is no risk of oil leakage, they do not cause environmental pollution. This feature makes it an ideal choice for projects that prioritize environmental sustainability.

Indoor Applications: Dry type transformers are perfect for indoor applications. Since the risk of fire is low, they can be used safely inside buildings. This is a significant advantage, especially in places such as commercial buildings, shopping malls and offices.

Resistance to Humidity and Corrosion: Dry type transformers are suitable for use in humid and corrosion resistant areas. This feature allows these transformers to be used safely in seaside areas or areas with high humidity.

Less Maintenance Requirement: Dry type transformers have less maintenance requirement. Since routine maintenance operations such as oil changes are not required, operating costs are lower and operational continuity is higher.
