Prefabricated Cabinetype Selection Principles

(1) The exterior design is aesthetically pleasing and harmonious with the external environment. For example, the container’s exterior should be as simple as possible, with reasonably sized and positioned components like air conditioners and air vents. The container’s color should coordinate with surrounding transformers and high-voltage switchgear.
(2) The dimensions of the cabinetype should balance equipment transportation and inspection requirements, layout needs, and transportation constraints.
(3) Minimize external wiring for the prefabricated cabinetype by designing unified interfaces.
(4) The layout of panels and equipment within the cabin should be rational, striving to maximize space for operational and maintenance access.
(5) Equipment installation and wiring within the prefabricated cabinetype should be completed as much as possible at the factory, with on-site work focused primarily on connecting the cabin to external equipment.

Advantages of Prefabricated Cabins

• Significantly reduce on-site “wet” construction work, shortening the civil engineering cycle for substation construction.

• Integrated design and testing of primary and secondary equipment.

• Modular equipment design, factory customization, and on-site combinatorial assembly enable “plug-and-play” functionality.

• Greatly reduce the workload for on-site construction and commissioning, shortening the commissioning time.
