ABB Oil Cooled Transformer 100 kVA 33kV/11kV

An ABB Oil Cooled Transformer with a rating of 100 kVA and voltage levels of 33 kV/11 kV is a three-phase distribution transformer designed to step down high voltage from 33,000 volts to a lower voltage of 11,000 volts. It uses oil as a cooling medium to maintain optimal operating temperature and enhance longevity by efficiently dissipating heat. The transformer typically has copper windings, is insulated with mineral transformer oil, and housed in a robust mild steel tank that provides mechanical protection and contains the cooling oil. It is suitable for outdoor mounting and includes features such as conservator tanks, Buchholz relays, thermometer with contacts, and tap changers to regulate voltage variation. This type of transformer is commonly used in industrial and utility power distribution to convert high voltage electricity to a lower voltage suitable for industrial and residential use. It conforms to IEC standards for transformers, ensuring high reliability, durability, and energy efficiency in various applications.
