Unit Substations
Introduction to Unit Substations
Pre-Assembled, Mobile Power Solutions for Industrial Projects
Unit substations are pre-fabricated power distribution systems that integrate a transformer, medium voltage (MV) panel, and low voltage (LV) panel in a single, transportable structure. Designed for fast deployment, space efficiency, and portability, they offer an ideal solution for projects requiring temporary, modular, or mobile power distribution. Iran Transfo Substation Development manufactures these units with flexible engineering and a variety of voltage and capacity options.

FAQ
- What is a unit substation?
- A unit substation is a pre-assembled, all-in-one power unit that includes a transformer and MV/LV switchgear in a transportable structure.
- How is a unit substation different from a compact substation?
- Unit substations are often more mobile and suited for temporary or open-space installations, while compact substations are enclosed and designed for urban environments.
- Does a unit substation require a foundation?
- Typically, it is mounted on a concrete slab or metal base with minimal civil works required.
- Where are unit substations commonly used?
- They are ideal for construction sites, industrial zones, temporary camps, and small-scale power plants.
- Can unit substations be customized?
- Yes, Iran Transfo designs them based on voltage, capacity, layout, and environmental requirements.
