Oil-tight transformers of the TMG series, with a capacity from 25kVA to 1600 kVA (6.10)
Hermetically sealed transformers are manufactured with full oil filling, without an expander, and without an air or gas cushion. The advantages of TMG transformers are energy saving, compactness, environmental friendliness and durability in operation. There is no contact of the oil with the environment, which eliminates moisture, oxidation and slag formation of the oil. Before filling, the oil is degassed , filling into the tank is carried out in a special vacuum filling chamber, which greatly increases the electrical strength of the transformer insulation. The oil in hermetically sealed transformers practically does not change its properties during the entire service life.
