Product Overview

The S-10000/12.47/4.16&2.4&2.4 is a three phase outdoor substation power transformer with a 10/11.2/12.5/14 MVA ONAN/ONAF rating. It is configured for 12470V Delta primary input and multiple medium-voltage secondary outputs, including 2400V Delta, 2400Y/1385V Wye and 4160Y/2400V Wye, making it suitable for utility distribution substations, industrial plants, pump stations, renewable project substations and large outdoor distribution networks that require both 2.4kV and 4.16kV power levels.

Built with mineral oil insulation, aluminum windings, silicon steel core, side-mounted ATC terminal chambers, porcelain bushings and a 7-position off-load tap range from 14400V to 11500V, the transformer helps match site voltage conditions while maintaining medium-voltage distribution flexibility. The ANSI C57.12.00 design, HV BIL 110kV, LV BIL 60kV and 55/65/55F/65F°C temperature rise support outdoor substation operation where insulation coordination, voltage adjustment and load-stage flexibility are important.

Product Advantages


  • Multi-Capacity ONAN/ONAF Cooling Structure
    Rated at 10/11.2/12.5/14 MVA, this transformer uses radiator banks and cooling fan assemblies to support ONAN/ONAF operation. It helps customers cover normal load and fan-assisted peak demand with one unit, reducing the need for immediate transformer replacement when load requirements increase.


  • Multi-Voltage Secondary Design
    Configured with 12470V primary input and 2400D, 2400Y/1385V and 4160Y/2400V secondary outputs, the transformer helps customers match different medium-voltage distribution requirements with one flexible design.
   

  • Side-Mounted HV and LV ATC Terminal Chambers
    Side-mounted HV and LV ATC chambers provide accessible cable termination space for outdoor substation layouts, helping customers simplify field wiring, inspection and maintenance.
