| Model NO. | Compact Prefabricated Substation (European Type) 100 - 1250kVA |
| Rated voltage | 10kV |
| Series | YB-10 |
The Prefabricated Substation is an integrated modular power distribution solution that assembles high‑voltage switchgear, transformers and low‑voltage switchgear into one compact unit. This Compact Prefabricated Substation features highly integrated layout and reliable operation, widely applied in urban high‑rise buildings, residential communities, industrial parks, medium and small factories, mining areas, highway projects and temporary construction sites.
With high integration and compact structure, the Prefabricated Substation delivers stable performance, easy maintenance and convenient mobility. The Compact Prefabricated Substation only occupies 1/10–1/5 floor space compared with traditional civil substations of the same capacity, greatly simplifying design work, reducing construction volume and cutting overall project cost.
The Prefabricated Substation is highly flexible in system matching, adaptable to ring network distribution, dual power supply and radial terminal distribution modes. As an advanced modern power distribution solution, the Compact Prefabricated Substation is widely adopted in urban and rural power grid renovation and upgrading, becoming mainstream compact substation equipment for new‑generation power systems.
The Prefabricated Substation adopts a three‑compartment integrated layout: high‑voltage room, transformer room and low‑voltage room, ensuring independent operation, safe isolation and flexible configuration of the Compact Prefabricated Substation.
The Prefabricated Substation supports ring network, terminal and dual power supply operation modes.
Optional high‑voltage metering configuration meets precise energy measurement demands.
Compact rational layout with complete anti‑misoperation interlock ensures safe running of the Compact Prefabricated Substation.
The Prefabricated Substation is compatible with both oil‑immersed and dry‑type transformers for flexible selection.
Optional rail mounting design enables easy transformer replacement and maintenance through side doors.
Automatic temperature control ventilation (natural + forced air) keeps the Compact Prefabricated Substation operating steadily under varying load conditions.
Customizable panel and cabinet structure adapts to diverse power distribution demands of the Prefabricated Substation.
Integrates power distribution, lighting control, reactive power compensation and energy metering in one unit.
Optimizes power supply management efficiency and improves overall power quality for the Compact Prefabricated Substation.
