As a specialized transformer manufacturer, we supply two core product families: Cast Resin Dry-Type Transformers and Oil-Immersed (Liquid-Filled) Distribution Transformers. Both are engineered for low losses, high thermal stability, and long service life. The technical comparison below is written from an engineering perspective to help you select the correct unit based on installation environment, fire safety requirements, and total cost of ownership (TCO).
Typical Applications
Indoor substations (shopping malls, hospitals, high-rise buildings)

Data centers (1250kVA – 2500kVA recommended for PUE reduction)

UPS input and non-linear load environments (Dyn11 vector group)

Renewable integration points requiring indoor placement.
Available Options Across Both Transformer Families
Tapping range: ±2×2.5% or ±5% on HV side

Vector group: Dyn11 (default for 3-phase 4-wire systems), Yyn0, Yd11

Impedance voltage: 4% / 6% / 8% (higher values for fault current limiting)

Enclosure / protection level: IP00 (open), IP20, IP23, IP54 (dry-type only)

Temperature monitoring: PT100 sensors + digital controller with alarm and trip functions

Accessories: Rollers, bottom drip tray, forced cooling fans (AF), surge arrester.
