the step-up substation for the coastal solar power project in Guatemala.
For export projects, we adopt a flexible and tailored approach.
The unique aspects of this project are:
1. High voltage rating of 34.5 kV/690 V, with a large capacity ranging from 3 MVA to 4 MVA;
2. Requirements for high-temperature resistance and resistance to salt spray corrosion in a coastal environment;
3. Convenience for container loading and transshipment via sea freight.
Final design:
* 3.5M/36 kV product dimensions of 5.8× 2.2 × 2.45 m;
* two units fit exactly into a 40-feet standard container.
* After maximizing space efficiency, the corrosion protection rating must meet C5 (IP65);
only low-voltage switchgear equipped with internal circulation air conditioning can ensure compliance with temperature rise limits.
