YB -40.5 Prefabricated Cabin Substation by Trusted China Suppliers | High-Quality Factory Designs for Optimal Integration
Overview of development status
Prefabricated cabin-type combined equipment was studied and applied abroad at an early time. In the mid-1980s, it was applied to the overall modular 33kV substation in the United States; in the 1990s, the overall modular 66kV substation in Japan also applied prefabricated equipment cabins. The container-type electrical hut launched by ABB has been widely used in the Middle East countries.
In China, 35kV and 10kV box-type substations have been widely used in projects, and containerized SVG equipment, containerized DC ice melting equipment, and containerized photovoltaic inverters are also widely used.
In 2013, State Grid Corporation of China launched the construction of a new generation of intelligent substation demonstration project, and proposed the construction principles of "standardized design, factory processing, modular construction, and mechanized construction". According to this principle, in the new generation of smart substations, there are almost no buildings, instead there are prefabricated cabin-type combined equipment.
In the State Grid Corporation's new generation of intelligent substation demonstration project, Chongqing Dashi 220kV substation and Hubei Future City 110kV substation are AIS substations, both of which use prefabricated cabin-type combined equipment.
The construction of the new generation of intelligent substations has accumulated valuable experience in the application of prefabricated cabin-type combined equipment, and actively guided domestic equipment manufacturing companies to carry out equipment research and technological innovation.
Selection principles
-
Beautiful and Harmonious Appearance: The appearance of the container should be as simple as possible, the size and position of the air conditioner, inlet and other parts should be reasonably designed, and the color should be coordinated with surrounding transformers and high-voltage switchgear.
-
Optimized Dimension Selection: The selection of cabin box size should carefully take into account the equipment transportation requirements, plane layout requirements, and transportation regulations.
-
Unified Interface Design: Minimize external wiring of prefabricated cabins and design a unified interface for easier integration.
-
Reasonable Screen Layout: Expand the space for operation and maintenance channels as much as possible to ensure efficient workflow.
-
Minimized On-Site Workload: Equipment installation and wiring in the prefabricated cabin should be completed in the factory as much as possible, leaving only external connections for the site.
Product Benefits
Uses advanced, safe, and reliable technology. Features a maintenance-free cabin structure, micro-positive pressure air conditioning, and a dust-free, constant temperature/humidity environment.
Highly optimized spatial design requiring a minimum equipment area of only 340m² and a minimum site area of 416m².
All equipment installation, wiring, and commissioning processes are fully completed within the factory environment.
Substantially shortens the project timeline, with a site building cycle of only 3 to 6 months.
Minimal on-site debugging required. The equipment can be fully put into operation within 15 to 30 days after arrival.
Utilizes advanced sound barrier technology to significantly reduce transformer operation noise.
Fully enclosed metal casing design effectively blocks and reduces electromagnetic radiation.
Main components are completely maintenance-free. The cabin offers 30-year rust-proof performance and a 60-year service life.
Integrated design concept of cabins and cabinets with a modular block structure that harmonizes with urban styles.
No rooms, no walls, no structures, no radiation, no noise, and no manual on-duty requirement.
Building block style modular structure offering highly flexible configuration layouts.
Factory commissioning
We simulate on-site substation construction directly in the factory to verify the structural design, which greatly improves the efficiency of on-site construction. The primary system joint debugging, secondary system joint debugging, and overall joint debugging are fully completed in the factory. We also jointly conduct on-site acceptance with the customer's acceptance department and the supervision unit.
Delivery transportation
The prefabricated cabin is transported and delivered as a whole, and hoisted as a single unit, making the process convenient and fast. Prefabricated cabin modules are engineered to meet the over-limit requirements of external dimensions for road, rail, and sea transportation.
Prefabricated construction
The building block construction mode minimizes the on-site construction workload. The large cabin is constructed in modular sections in the factory and assembled in modular sections on site, which greatly shortens the construction period. By abandoning traditional on-site "wet method" construction, we save water resources and protect the ecological environment. The overall quality level and safe operation level of the project are improved, achieving cost optimization, energy conservation, and environmental protection to the greatest extent.
