Free Breathing Oil Filled Transformer

The free breathing transformers are equipped with a cushion under the cover or a conservator to allow the oil to expand, at the temperature variations. As it is not hermetic, the oil is always in contact with the air. Moisture is kept at bay through the use of dehydrating salts contained in special filters (breather). The tank can be in finned or with radiators. This design applies to all powers, but especially from 4000 kVA and up. For higher powers and to avoid contact between the oil and air, a rubber separator (rubber bag) or a nitrogen cushion is used.

Power 50 kVA – 50MVA
Voltage Class 1.1kV – 145kV
Material temperature classes A , F
Environmental temperature -60 a + 60
winding materials aluminium or copper
Oil Mineral, silicone, ester or vegetable type
Accessories Overpressure valve, thermometer, oil level, anti-vibration device, protective boxes
Strengths Outdoor installation for any environment, even if aggressive, low maintenance compared to the hermetic transformer, easy to fill with oil
