The 200 kVA 3 Phase Step Down Transformer<\/a> is a durable and energy-efficient solution for medium-voltage to low-voltage conversion in commercial, industrial, and municipal distribution networks. Engineered for 11 kV primary and 400 V secondary voltages, this oil-immersed transformer is ideally suited for use across European and international 50 Hz power grids. Its grounded Wye secondary ensures balanced loads and safe neutral availability, making it an optimal choice for applications requiring reliable three-phase distribution.<\/p>\n Manufactured by Energy Transformer<\/a>, a certified power transformer supplier with over 30 years of experience, this unit features a precision-engineered magnetic core built with cold-rolled grain-oriented silicon steel (CRGO) and oxygen-free copper windings for superior conductivity and low core losses. The transformer tank is filled with high-grade mineral insulating oil that provides long-term thermal and dielectric stability, with optional biodegradable or fire-resistant fluids available.<\/p>\n Designed to meet or exceed international standards such as IEC 60076, ANSI C57, and IEEE, the transformer is enclosed in a hermetically sealed steel tank coated with anti-corrosion paint for maximum protection against moisture, salt spray, and mechanical wear. Built-in protection features include a temperature indicator, oil level sight glass, pressure relief valve, and optional gas relay for enhanced safety.<\/p>\n
