Before customizing a transformer enclosure, provide the transformer type, model, capacity, dimensions, weight, installation site, foundation dimensions, cable entry/exit orientation, ventilation requirements, door orientation, maintenance clearance, and order quantity.

For outdoor installations, also include ambient temperature, humidity, corrosion conditions, target protection rating, and surface treatment requirements. If fire protection, noise reduction, or equipment isolation is involved, specify relevant project standards and test criteria. Complete transformer drawings, site photos, and foundation data help confirm structural design, pricing, and production scope.
