EU Box-type substation is also called prefabricated substation or prefabricated substation. It is a kind of factory-prefabricated indoor and outdoor compact power distribution equipment with high-voltage switchgear, distribution transformer and low-voltage power distribution device arranged according to a certain wiring plan.

It organically combines the functions of transformer step-down and low-voltage power distribution. Together, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box. It is especially suitable for the construction and transformation of urban power grids. It is a new type of steel structure box that has emerged after civil engineering substations.

Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution rooms and distribution stations and becomes a new complete set of power transformation and distribution devices.
