 Power transformers; small/large oil immersed distribution, med/large power transformers, tranction, mining , dry type transformers, grounding and auxiliary transformers. No-load tap changer or automatic tap changer, both outdoor and indoor designed at form. Pressure of the oil changes in consequences thermic effects. The slica (air dryer) that being on conservator tank is got humidity of the air and it provides ingress-egress of the air. Slica gel transformers with oil conservator tank that works in the enterprise loses its feature in the course of the time. Structure of core and windings of transformers with oil conservator tank is same with hermetically sealed transformers. Since there is not the conservator tank on hermetically sealed transformersi their heights are smaller than transfoırmers with oil conservator tank and therefore they are used smaller in fields. The oil of hermetically sealed transformers is no necessary to changing in specific periods since the oil does not contact with atmosphere. Structure of core and windings of transformers with oil conservator tank is same with hermetically sealed transformers.
