Highly integrated & factory prefabricated: HV cabinet, transformer and LV cabinet are fully assembled in factory. Only foundation and cable connection are required on site, greatly shortening construction time.
Space-saving: Occupies over 60% less land than conventional masonry substations, perfect for projects with limited land.
Modular structure: Flexible layout and easy expansion. European type adopts separate compartments for HV, transformer and LV for safer maintenance.
All-weather outdoor performance: Anti-corrosion enclosure, rainproof and dustproof, stable operation under high temperature, freezing and sandy field conditions.
Convenient maintenance: Observation windows and external operating mechanisms allow switching and parameter inspection outside the enclosure.
Cost-effective: Less civil work, lower overall project investment compared with traditional indoor substations.
Note: Pad-mounted (American type) has more compact design with transformer, load switch and fuses in one oil tank. European compact substation has independent separated compartments.
