Prefab Cabins & Control Boxes — Buyer Questions

Straight answers to what buyers ask us most.

What are prefabricated substation containers used for?
They house transformers, switchgear or control equipment in a factory-built, weatherproof and lockable enclosure — deployed in weeks instead of the months a brick building takes.
Is an explosion-proof cabin certified?
The Ex-rated cabin uses explosion-proof ventilation, lighting and wiring glands, built to the classification you specify. Send the hazardous-area classification and we confirm compliance before production.
How is a prefab cabin transported?
Standard ISO footprint so it ships like a container, with corner castings for lifting. Oversize cabins ship as knock-down panels assembled on site.
What is the lead time?
15–30 days for standard cabins, 30–45 days for explosion-proof or electrically fitted units, plus sea freight time to your port.
