The size of drytype transformers varies primarily by rated capacity, cooling method (aircooled/forced aircooled), and structural design (e.g., resincast, opentype). Below is a concise reference for common specifications:

　　Core Size Range (Length × Width × Height, mm)

　　Small capacity (5–100 kVA)

　　5kVA: ~600×400×700

　　50kVA: ~850×550×950

　　100kVA: ~1000×650×1100

　　Medium capacity (125–630 kVA)

　　200kVA: ~1200×750×1300

　　400kVA: ~1500×900×1600

　　630kVA: ~1800×1100×1900

　　Large capacity (800–2500 kVA)

　　1000kVA: ~2200×1300×2300

　　2000kVA: ~2800×1600×2800

　　2500kVA: ~3200×1800×3200

　　Key Influencing Factors

　　1. Capacity is the primary driver—larger capacity requires more core material and winding space, increasing overall dimensions.

　　2. Cooling method: Forced aircooled models add fans, slightly expanding width/depth vs. natural aircooled.

　　3. Manufacturer differences: Structural optimizations (e.g., compact winding design) can reduce size by 5–15% for the same capacity.

　　Do you need a detailed size table for a specific capacity range (e.g., 100–500 kVA) or brandspecific data? I can compile a customized dimension list tailored to your needs.
