Dimensions of the Containerized Electrical Assembly Box

Containerized electrical assembly boxes, such as eHouses or modular substations, are typically designed in transportable dimensions but can be customized, with standard modules ranging from single ISO container sizes to multi-unit assemblies.

Typical Dimensions

Containerized electrical assemblies are often based on ISO container standards for transportability, with common single-unit dimensions approximately: Length: 6–12 meters (20–40 feet)Width: 2. 4–2. 5 meters (8 feet)Height: 2.

6–3 meters (8. 5–10 feet) These dimensions allow for road transport and maritime shipping while housing medium and low voltage switchgear, transformers, and auxiliary equipment.

Modular and Multi-

Unit Configurations

For larger installations, containerized electrical boxes can be modular, consisting of multiple steel units joined on-site to form a single building. Each module maintains transportable dimensions, and the combined structure can be configured with: Multiple rooms for switchgear, control systems, and auxiliary equipmentAccess points and internal subdivisions for maintenance and operational safetyStacked or coupled units to increase internal space without exceeding transport limits Customization OptionsManufacturers often provide customized dimensions to meet specific project requirements, including: High insulation or ATEX-rated enclosures for extreme environmentsHVAC systems, fire detection, and suppression systems integrated within the containerAirlock or pressurization systems for dusty, desert, or hazardous areasFlexible internal layouts for transformers, MCCs, PLCs, and UPS systems ConsiderationsTransport limitations: If a single module exceeds road or maritime transport limits, the structure can be split into smaller units for on-site assembly.

Internal usable space: Wall thickness, insulation, and installed equipment reduce the effective internal volume compared to external dimensions. Environmental adaptation: Roofs, gaskets, and pressurization systems are designed to maintain operational conditions in aggressive or remote environments. In summary, containerized electrical assembly boxes are highly flexible in size, ranging from standard ISO container dimensions to large multi-unit modular assemblies, with customization options to meet transport, environmental, and operational requirements.
