Prefabricated Substation
Prefabricated Substations for Power Distribution Projects
Huamei Electric manufactures prefabricated substations for industrial facilities, utility distribution networks, infrastructure projects and EPC electrical projects.
A prefabricated substation integrates high-voltage equipment, transformer equipment and low-voltage distribution equipment into a compact enclosure or factory-assembled unit. Compared with conventional site-built substations, this type of solution can simplify project installation, reduce on-site construction work and provide a compact power distribution arrangement for locations where space and construction efficiency are important.
Huamei Electric provides both European-style and American-style prefabricated substation solutions according to different electrical system and project requirements.
Available Prefabricated Substation Solutions
Our current prefabricated substation range includes:
- YB-12 European Style Prefabricated Substation
- ZGF28-12 American Style Prefabricated Substation
- Outdoor prefabricated substations
- Ring network distribution configurations
- Terminal distribution configurations
- Customized high-voltage and low-voltage arrangements
The final configuration can be selected according to project voltage level, transformer capacity, high-voltage switchgear scheme, low-voltage outgoing circuits, protection requirements and installation environment.
European Style Prefabricated Substation
The YB-12 European-style prefabricated substation combines high-voltage electrical cabinets, transformer equipment and low-voltage electrical cabinets into an integrated power distribution unit.
It can be applied in urban and rural distribution systems, residential and commercial developments, industrial facilities, mines, temporary construction power systems and other power distribution projects.
The integrated design can reduce the space required for the substation and simplify part of the on-site construction work compared with conventional civil-engineering substations.
Different enclosure structures and electrical configurations can be selected according to project requirements.
American Style Prefabricated Substation
The ZGF28-12 American-style prefabricated substation is designed as an integrated distribution unit combining high-voltage control, protection, transformer and low-voltage distribution functions.
It can be configured for ring network or terminal power supply applications.
Depending on the project design, the transformer, high-voltage switching components, protection devices, cable connection arrangements and low-voltage outgoing circuits can be configured to meet different distribution system requirements.
American-style substations are commonly considered where compact installation and integrated outdoor power distribution are required.
Key Information for Substation Selection
Selecting a prefabricated substation requires confirmation of both transformer parameters and the complete high-voltage and low-voltage system.
Important project information normally includes:
- Rated system voltage
- Transformer capacity
- High-voltage input voltage
- Low-voltage output voltage
- Frequency
- Transformer type
- High-voltage switchgear configuration
- Number of low-voltage outgoing circuits
- Protection requirements
- Cable entry and exit arrangement
- Enclosure requirements
- Installation environment
- Quantity
- Destination country
- Project application
For EPC projects, a single-line diagram or electrical specification is especially useful because the prefabricated substation is a complete distribution system rather than an individual transformer.
Applications of Prefabricated Substations
Prefabricated substations can be used in a wide range of power distribution projects, including:
- Industrial factories
- Commercial developments
- Residential communities
- Mining projects
- Infrastructure projects
- Urban and rural distribution networks
- Construction sites
- Renewable energy projects
- Industrial parks
- EPC power projects
The actual configuration should be determined according to electrical load, text load, voltage level, protection scheme, installation conditions and project standards.
Manufacturing and Project Configuration
A prefabricated substation project normally requires coordination between transformer equipment, high-voltage switchgear, low-voltage distribution equipment, enclosure structure and protection components.
Huamei Electric can review project specifications and electrical drawings to confirm the required configuration before production.
According to project requirements, technical drawings, equipment datasheets, component configurations and testing documents can be prepared for technical confirmation.
Request a Prefabricated Substation Proposal
To prepare a technical proposal and quotation, please provide the transformer capacity, high-voltage and low-voltage ratings, frequency, high-voltage scheme, number of low-voltage outgoing circuits, quantity, application and destination country.
If you already have a single-line diagram, technical specification, equipment schedule or project drawing, please submit it for engineering review.
