European-style box-type substation (combined substation) is a complete set of power distribution equipment that integrates high-voltage switchgear, transformers, low-voltage distribution equipment, low-voltage intelligent switches, and automatic reactive power compensation, and is combined in a certain wiring scheme. It has the functions of local or remote operation to achieve remote control, remote measurement, remote metering, and remote regulation. The combined substation can be used both outdoors and indoors, and is widely applied in industrial parks, residential communities, commercial centers, public places, airports, docks, subways, hotels, schools, hospitals, construction sites with high mobility, mines, oil fields, and temporary power supply scenarios.

The combined substation has the following advantages:

Fully functional and reliable

It can cut off short circuits and load currents, and provide full-range current protection. For high voltage, there are multiple power supply methods available for selection, such as ring network (including dual power supply), terminal, and with high-voltage metering. It possesses all the functions of traditional civil construction substations.

Low investment, small land occupation, easy installation and quick effect

Cost-saving: It requires less capital investment than distribution transformers and distribution rooms. Land-saving: Small in size, approximately one-third or less of the volume of a distribution transformer and distribution room of the same capacity. Time-saving: It can be delivered within less than one month. The on-site installation is simple. Only four installation bolts need to be tightened and the incoming and outgoing cables need to be connected on site.

Good safety

It adopts a fully enclosed design. The product shell is grounded and there are no live parts on the outer surface. Therefore, there is no need for insulation distance, which can reliably ensure personal safety. It is convenient to move and can be relocated as a whole from one location to another as needed.
