Application scenarios:
- Urban Civil Power Distribution : Residential communities, commercial complexes, office buildings, hospitals, schools, and municipal street lighting—replacing traditional brick-and-mortar substations.
- New energy industry : Ground-mounted photovoltaic power plants, distributed PV, wind power projects, and energy storage substations for step-up transformation / On-site distribution unit.
- Industrial plant electricity consumption : Main power distribution for small and medium-sized factories, industrial parks, mines, oilfields, and chemical plants.
- Infrastructure Temporary / Permanent electricity use : Temporary power supply at construction sites, high-speed railway stations, airports, port terminals, and supporting distribution systems for rail transit.
- Public Landscape Area : Used in urban parks, green belts, and scenic areas as landscape‑style features. YB-12 Box-type substations enhance the urban landscape.
Product Advantages:
- Highly integrated, with extremely simple installation. : The equipment is pre‑wired and fully commissioned at the factory; on site, only basic installation is required. + Simply connect the cables to supply power, shortening the construction timeline. 70% That is all.
- Extremely compact footprint, flexible site selection. : It occupies only a fraction of the land area of a conventional substation. 1/10~1/5 It can be installed in green belts, road corners, and load centers, thereby shortening the low-voltage supply radius and reducing line losses. taisa.com....。
- Three separate isolation rooms, with a high safety standard. : The high-voltage compartment, transformer compartment, and low-voltage compartment are completely separated by metal partitions; each compartment features independent pressure relief and independent ventilation, preventing fault propagation between compartments. The entire system is equipped with a comprehensive five‑prevention mechanical interlocking mechanism to eliminate the risk of misoperation.
- Outdoor all-weather durability : The enclosure features a double-layer roof for thermal insulation and rain protection, with an all‑steel hot‑dip galvanized anti‑corrosion finish. It is resistant to sun and rain, corrosion‑proof, and protects against rodents and insects, ensuring an outdoor service life of up to 20 More than years.
- Convenient operations and maintenance, with strong intelligent scalability. Each compartment features independent access for maintenance and can be equipped with temperature monitoring, partial discharge detection, remote measurement and control, and wireless communication modules, making it suitable for unattended distribution‑network management.
- Attractive appearance, customizable. The enclosure can be finished to mimic stone, wood grain, or painted landscape designs, seamlessly blending into urban greenery and architectural landscapes.
- Diverse power supply solutions : Supports ring‑network power supply, terminal‑type power supply, and dual‑source automatic transfer switching, adapting to various urban grid topologies.
