oil cooled distribution transformer
Oil cooled distribution transformers are essential electrical devices that serve as the backbone of power distribution systems, efficiently transferring electrical energy between circuits while maintaining different voltage levels. These transformers utilize mineral oil as both a cooling medium and electrical insulator, ensuring optimal performance and longevity. The oil serves multiple critical functions: it dissipates heat generated during operation, provides excellent electrical insulation, and protects internal components from oxidation and degradation. The transformer's design includes a sealed tank filled with specially refined mineral oil, radiators for heat dissipation, and internal windings made of high-grade copper or aluminum. The cooling system operates through natural convection, where heated oil rises to the radiators, cools, and descends back to continue the cycle. These transformers are available in various power ratings, typically ranging from 50 kVA to 2500 kVA, making them suitable for diverse applications in residential, commercial, and industrial settings. Their robust construction and reliable operation make them particularly valuable in outdoor installations, where they must withstand varying weather conditions while maintaining consistent performance.
