A compact substation, also known as a prefabricated electrical substation, is an integrated and standardized unit designed for the transformation and distribution of electrical energy from medium voltage (MV) to low voltage (LV). All essential network equipment is installed within this unit in a consolidated and engineered manner. These substations are designed and manufactured with the objectives of enhancing safety, minimizing space occupation, and accelerating the installation and operational processes.

In a compact substation, the equipment, including the medium voltage (MV) switchgear, power transformer, and low voltage (LV) switchboard, is housed within a protective metal or concrete enclosure. They are assembled in accordance with technical requirements and reputable international and national standards.

———– Main Components of a Compact Substation ———-

• Medium Voltage (MV) Switchgear: Includes switching, protection, and control equipment for the network.
• Distribution Transformer: Used to convert medium voltage to low voltage.
• Low Voltage (LV) Switchboard: Distributes electrical energy and provides protection for outgoing feeders.
• Substation Enclosure and Structure: Metal or concrete, with appropriate protection rating against environmental factors.

——————– Features and Advantages ——————–

• Compact design, occupying minimal space.
• High safety level for personnel and equipment.
• Reduced installation and commissioning time at the project site.
• Operability in outdoor environments and various climatic conditions.
• Compliance with IEC standards and Iranian National Standards (INSO).

———————— Application Areas ————————

• Residential and commercial building projects.
• Administrative complexes and service centers.
• Industrial units and industrial zones.
• Infrastructure and civil engineering projects.
• Local electricity distribution centers.
