A prefabricated substation, also known as a substation in a box,integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment. It is primarily used for voltage transformation in the power system, converting high-voltage electrical energy from transmission lines into low-voltage electrical energy suitable
for consumer use. It distributes the energy stepped down by the transformer to various electrical units, ensuring effective allocation of electrical energy.
The substation in a box is equipped with a control system for monitoring and controlling the operation of the substation. It also has overload protection and short-circuit protection functions to ensure the safe operation of electrical equipment. It is mainly used for urban power grid construction and renovation, temporary power supply, power system expansion, replacement of traditional substations, and power supply needs in remote areas.Pre-installed substation(European)
