Fully Buried All-Concrete Substations
Introduction to Fully Buried All-Concrete Substations
Safe, compact and durable power solutions for underground installations
Fully buried all-concrete substations by Iran Transfo Substation Development Co. are engineered for complete underground installation, offering optimal space utilization, aesthetic integration, and high safety. These substations are constructed entirely from reinforced concrete, ensuring exceptional mechanical strength, long service life, and resistance to environmental factors. They are particularly suitable for dense urban areas, metro systems, infrastructure projects, and industrial zones where above-ground space is limited or visual impact must be minimized. The fully integrated enclosure allows secure housing of MV switchgear, transformer, and LV panels while providing ease of access for maintenance through surface hatches.
