Detailed information about the YBP series box-type substation
1. Introduction to the product
The YBP series box-type substation (European type) is an outdoor integrated power supply equipment, which largely combines high-voltage switchgear, distribution transformer and low-voltage switchgear.
It features an I-shaped or triangular layout, with separate rooms for high-voltage equipment, a transformer substation, and low-voltage equipment. Its advantages include complete electrical insulation, safe operation, and ease of maintenance.
All equipment is manufactured, assembled, and tested at the factory. Commissioning requires only on-site connection to the power grid, significantly reducing construction time. It is widely used to replace traditional civil substations and is the preferred equipment for urban networks, residential areas, industrial zones, and other outdoor power supply projects.

3. Main characteristics
Modular design and rational layout
An independent three-section design, isolating the high-voltage, transformer, and low-voltage systems from each other. Mechanical interlocking ensures safe and easy operation and maintenance.
Factory assembly and quick setup of equipment.
All components are assembled, insulated, and tested at the factory. On-site work only requires foundation support and cable connections, after which the facility can be commissioned within 3–5 days.
High level of safety and security
Equipped with a full five-stage lock to prevent misuse. The housing is made of high-quality steel or aluminum alloy with anti-corrosion treatment, providing dust, moisture, corrosion, and UV protection for outdoor use in all weather conditions.
It does not require maintenance and has low operating costs.
Reliable sealing, moisture, dust, and condensation protection. Long service life without maintenance. An intelligent monitoring system can be installed for remote measurement, communication, and control, ensuring automated operation.
Flexible movement and easy expansion
Compact in size, they occupy only 1/5–1/10 the space of traditional substations. They are easy to lift and move. Capacity can be quickly increased by replacing the transformer or adding outgoing lines.
4. Application scenarios
Urban civil buildings
Residential areas, office buildings, shopping centers, hotels, schools, hospitals – suitable for power supply of outdoor distribution boards.
Industrial production
Factories, industrial parks, mines, construction sites, metallurgical and chemical bases suitable for work in harsh conditions.
Municipal and infrastructure
City roads, parking, metro, airports, ports, scenic spots, reconstruction of urban and rural power grids.
Special Environments
Coastal areas (resistant to salt fog), areas with high humidity and dust, field camps with high adaptability to the environment.
