All Transformers suppliers from Ukraine

TM oil transformers are produced with a capacity from 25 to 1000 kVA for a rated voltage of the primary winding of 6 or 10 kV and a rated voltage of the secondary winding of 0.4 or 0.23 kV with a frequency of 50 Hz. Scheme and group of connections of windings U / Un-0 or D / Un-11. Type of climatic modification U1 in accordance with GOST 15150. Normal operation of transformers is ensured under the following conditions: 1. Height above sea level - no more than 1000 m; 2. Environment - non-explosive, not containing conductive dust, corrosive gases and vapors in concentrations that reduce the parameters of the KTP within unacceptable limits; 3. Wind speed up to 36 m / s (wind pressure speed up to 800 Pa); 4. Type of atmosphere - II in accordance with GOST 15150; 5. Ambient temperature - from -45 ° С to + 40 ° С. Voltage regulation is carried out by switching without excitation (PBV) when the transformer is disconnected from the mains, both on the high and low voltage sides. The voltage is regulated from the high voltage side by ± 2x2.5% of the nominal value. Outdoor transformer bushings, removable, porcelain bushing insulators. At currents of 630 and 2500A, contact clamps with a paddle are attached to the current-carrying rods, which ensures the connection of a bus or cable lugs. The oil conservator ensures the presence of oil in all operating modes of the transformer and fluctuations in ambient temperature, and also has a built-in air dryer with an oil seal. A thermometer is installed on the lid to measure the temperature of the upper layers of oil. Transformers with power from 400 to 2500 kVA are equipped with rollers. Transformers comply with GOST 116777 and technical specifications TU U31.1-31617591-001-1005.
