The S11-M series 100kVA oil immersed distribution transformer is expertly designed for highly reliable three-phase 50/60Hz power grids. Featuring a fully sealed corrugated tank construction, this unit isolates the insulating oil from the ambient air, which effectively prevents moisture absorption and oxidation. This advanced design significantly extends the service life and makes the transformer completely maintenance-free. Built with a high-permeability CRGO core and 100% copper windings, it guarantees high efficiency and low energy consumption. The unit seamlessly steps down a 10kV primary voltage to a stable 400V secondary voltage.
Manufactured to meet the most stringent international standards, including IEC 60076 and GB/T 1094, this transformer delivers stable and efficient power. It also comes with an 18-month warranty for guaranteed reliability. Below is the core datasheet for bulk procurement evaluation:
