Modern data centers demand continuous power availability, high efficiency, and maximum fire safety. Our Data Center Dry Type Cast Resin Transformers are engineered specifically for hyperscale, colocation, and enterprise data center applications, where stable operation under long-term high load is essential.
Designed and manufactured in accordance with IEC 60076 and IEC 60076-11, these transformers provide a safe, oil-free, and low-maintenance solution for medium voltage power distribution systems ranging from 10kV to 33kV.
Unlike conventional industrial transformers, data center transformers must operate reliably under:
Long-term load rates of 70–90%
High ambient temperature environments
Frequent load fluctuations caused by IT equipment
Strict fire safety and environmental requirements
Our cast resin dry type transformers are optimized to meet these challenges through advanced insulation systems, low-loss core design, and enhanced thermal performance.
Oil-free cast resin insulation eliminates fire and leakage risks
Self-extinguishing epoxy resin system
Suitable for indoor MV rooms and power distribution rooms
Optimized core material to reduce no-load losses
Low load losses to minimize energy consumption and OPEX
Designed for continuous full-load operation
Partial discharge ≤ 10 pC, ensuring insulation longevity
Low acoustic noise, suitable for noise-sensitive facilities
No oil, no pollution
Reduced maintenance and lower lifecycle cost
Our transformers are widely used in:
Medium Voltage (MV) distribution rooms
UPS input and bypass transformer systems
LV distribution systems feeding server halls
Prefabricated substations and E-House solutions
They integrate seamlessly with MV switchgear, LV panels, UPS systems, and backup generators.
