What is a Prefabricated Substation?
Substations are either transmission or distribution substations. Transmission substations step up the voltage to enter the grid, while distribution substations lower the voltage for consumer use. Prefabricated substations function as distribution substations but can also set up voltages when needed.
There are three main components within a substation– switchgear for higher voltages, distribution systems for lower voltages and transformers. Transformers receive energy at one voltage and then step the voltage up or down before distributing it. High-voltage switchgear manages higher voltages while a distribution system manages the distribution of lower voltages.

Applications
It’s also easy to manufacture to your exact specifications, which is helpful if you have a unique setup that may not work with a traditional substation.
Prefab substations are suitable for use in industrial, commercial and residential locations. They are suitable for factories, mines, construction zones and more. Rural neighborhoods and businesses may also find prefab substations suit their needs better than conventional substations.
Construction sites may opt for a prefabricated station as they can easily move between sites. Some industries with a substation may purchase a prefabricated system as a backup. Because prefabricated stations are so easy to take down and reassemble, they are often used as backup power when a conventional substation is undergoing maintenance and repairs.
