Hengfengyou Electrical Data Center Transformers: Providing Reliable Power Protection for Digital Infrastructure

Data centers, as the lifeblood of enterprise core operations, demand unprecedented reliability and efficiency in power supply. Leveraging 30 years of expertise in power equipment R&D and manufacturing, Hengfengyou Electric introduces power transformer solutions specifically engineered for modern data centers, delivering round-the-clock power assurance for facilities of all scales.

I. Overview of Data Center Power Transformers

Data center power transformers serve as the core and heart of the facility's power supply system. They undertake the critical task of converting high-voltage input from the external grid into usable voltages for internal equipment. Their reliability, efficiency, and performance directly determine the overall availability and power usage effectiveness (PUE) of the data center.

II. Design Specifications and Requirements for Data Center Power Transformers

1. Demands for Ultimate Reliability

Data center downtime costs can reach thousands of dollars per minute, requiring power equipment to deliver over 99.999% availability. Hengfengyou Electrical Transformers employ dual N+1 redundancy design and premium materials to ensure uninterrupted power supply.

2. Stringent Energy Efficiency Standards

Electricity costs account for over 40% of a data center's TCO. Our transformers reduce no-load losses by 15-20% below China's National Class 1 Energy Efficiency Standard, delivering significant annual power savings and effectively lowering clients' PUE values.

3. K-Rated Transformers

Harmonic pollution generated by data center server clusters severely impacts power quality. Our K20 series dry-type transformers employ specialized winding designs and K-rated manufacturing processes, withstanding over 30% harmonic currents. They deliver exceptional harmonic suppression capabilities, maintaining efficient and stable operation.

*Application Scenario Standards

K4: Traditional Lighting (＜20% non-linear load)

K13: Office Buildings/Server Rooms (75% computer equipment)

K20: Data Centers/Semiconductor Fab (100% precision instruments)

4. Fire Resistance & Flame Retardancy

Data center transformers operate continuously 24/7, generating substantial heat. This necessitates high-temperature tolerance and fire resistance, typically achieved through epoxy resin cast dry-type transformers.

Hengfengyou Electric's data center epoxy resin cast dry-type transformers offer the following advantages:

· Self-Extinguishing: Epoxy resin inherently possesses exceptional flame retardancy (typically achieving UL94 V-0 rating, one of the highest flame retardant classifications). Upon removal of an external ignition source, the material self-extinguishes without sustaining combustion.

· Suffocation Effect: Even during high-energy arc faults, epoxy resin may carbonize but does not produce flames or drip molten material. This confines the fault locally, preventing fire propagation.

5. Intelligent and Remote Monitoring Capabilities

Integrated sensors provide real-time monitoring of temperature, vibration, humidity, and other parameters. Support for multiple communication protocols including Modbus and BACnet enables seamless integration into SCADA systems, facilitating predictive maintenance and intelligent management. Analysis via IoT platforms enables fault early warning, extending service life by over 15%.

Ⅲ. Hengfengyou Data Center Transformer Solutions

Data centers predominantly utilize dry-type transformers, as oil-immersed units pose fire and leakage risks and are typically prohibited inside buildings.
