Functions and Features

1.Fully insulated and fully sealed, requiring minimal maintenance and ensuring reliable personal safety;

2.Compact structure with a volume only 1/3 to 1/5 of conventional substations of the same capacity, and low height;

3.Available in split-box structure to avoid oil contamination inside the transformer tank;

4.High-voltage side uses dual fuses for full-range protection, significantly reducing costs;

5.Suitable for both ring network and terminal applications; cable heads can be hot-plugged under emergency load current of 200A;

6.The enclosure adopts a honeycomb double-sandwich composite panel, providing both thermal insulation and heat dissipation functions;

7.Low-voltage side equipped with an electronic phase-loss protector that quickly disconnects the main incoming switch when abnormal voltage occurs in the system;

8.High-voltage side uses oil-immersed load switch or SF6 load switch, which can be upgraded to electric operation, laying the foundation for distribution network automation;

9.Adopts oil-immersed S9 or higher-performance S11 series transformers.
