Description

It differs from oil type transformers according to the cooling method. HV windings are transformers coated under vacuum with epoxy cast resin. LV windings are transformers that can be manufactured using both cast resin and resin-impregnated prepreg methods.

They are produced in the power range of 25-25000 kVA, up to 36 kV voltage level, with natural air cooling (AN) or fan cooling (AF) options. Up to 40% power increase can be achieved by using a cooling fan.

Dry type transformer manufacturing, which requires advanced technology and knowledge, is increasing its market share day by day compared to oil type transformers with increasing customer demands in recent years. However, in today’s technology, the production of high-power dry type transformers, especially above the 36 kV voltage level, poses technological difficulties. Research and development studies on this subject continue at full speed. It does not contain any environmentally harmful cooling liquid such as oil, it has less risk of fire, it does not require maintenance, it is resistant to humidity and humidity, it can be put into operation at any time without any problems even if it is not in operation for a long time, and it can be overloaded up to 40% of the nominal power with fan cooling reinforcement. It is preferred more than oil type distribution transformers for reasons such as. However, dry type distribution transformers, whose most important disadvantage is that their sales price is higher than an oil type transformer of the same power, have been constantly increasing their sales share in recent years.

You can obtain dry type transformers from 400 kVA to 2500 kVA from Aypars Energy, quickly and economically.
