The MINERA E00938 is a robust, mineral oil-immersed distribution transformer designed for reliable medium-voltage applications, featuring primary voltage ratings of 15 kV or 20 kV and secondary outputs of 400 V between phases (231 V phase to neutral), making it ideal for step-down power distribution. It offers a rated power range up to 630 kVA, with standard efficiency levels and optional liquid dielectric fittings. The transformer is built to EN 50464 standards, includes off-circuit tapping ranges of 2.5% or 5%, and supports vector groups such as Dyn11 and Yzn11 for flexible installation. Key technical specifications include a maximum insulation level of 24 kV for 20 kV models, impedance voltage typically between 4% and 6%, and no-load losses optimized for energy efficiency. The unit is housed in a galvanized, anti-corrosive tank with a bolted cover, ensuring durability in harsh environments. Dimensions and weight vary by kVA rating, with larger models designed for ground-mounted installation. For switchgear and protection, Krylon A01625 and similar components provide reliable circuit isolation and overload protection, with voltage ratings up to 690 V AC and current ratings from 20 A to 63 A, suitable for industrial and commercial electrical systems. These components are engineered for easy integration, safety, and long service life, meeting international standards for performance and reliability.
