Amid the accelerating global digital transformation, data centers, as the core of computing power, face critical challenges in energy efficiency and physical safety. Among the technological solutions addressing these challenges, solid-state transformers (SSTs) and cables utilizing aluminum hydroxide (ATH) as a key flame retardant play indispensable roles from the dimensions of power conversion and fire safety, respectively.
I. Solid-State Transformers: Revolutionizing Power Conversion Efficiency
Solid-state transformers are a new type of power transformation device based on power electronics technology. They replace the traditional iron core and copper windings of conventional transformers, achieving voltage conversion and electrical isolation through high-frequency power conversion.
Their core advantages deliver direct value to data centers:
1.High Power Density: The use of high-frequency magnetic components significantly reduces their physical size, freeing up valuable server room space.
2.Intelligent Power Management: Equipped with real-time regulation capabilities, they can actively improve power quality and provide cleaner electricity to server loads.
3.Enabling New Architectures: As an ideal interface between AC and DC power, SSTs are key components for building high-efficiency DC distribution systems and integrating distributed energy resources like photovoltaics and energy storage.
Industry practices show that the application of SSTs can effectively enhance the energy efficiency and flexibility of the power distribution segment in data centers, positioning them as a crucial technological direction for future green data centers.
II. Aluminum Hydroxide Flame Retardant: A Key Safeguard for Cable Safety
In the densely wired environment of data centers, the fire safety of cables is paramount. Aluminum hydroxide, an efficient and environmentally friendly inorganic flame-retardant filler, is widely used in low-smoke zero-halogen (LSZH) cables that meet stringent safety standards.
Its protective mechanism is achieved through the synergy of three physico-chemical actions:
Cooling Effect: Decomposes endothermically upon heating, absorbing significant heat and lowering the material's temperature.
Dilution and Suffocation: Releases water vapor, diluting flammable gases and oxygen.
Barrier Formation: Leaves a protective residue layer on the material surface.
The use of ATH-based flame-retardant cables can effectively suppress flame spread in the early stages of a fire while drastically reducing the production of toxic and corrosive smoke. This provides a critical window for personnel evacuation and protects sensitive IT equipment.
III. Synergistic Enhancement: Future-Oriented Infrastructure
The synergy between SST and ATH cable technologies is driving data center infrastructure toward greater efficiency and safety.
On one hand, new power distribution architectures promoted by SSTs, such as DC power supply, impose new requirements on the electrical performance and safety standards of cables. On the other hand, highly reliable, high fire-rating cables form the foundational line of defense ensuring the stable operation of all power distribution equipment, including SSTs.
Looking ahead, as SST intelligence advances, their integration with systems like cable temperature monitoring holds the potential to enable full-link intelligent management and predictive maintenance—from "source conversion" to "endpoint connection." Together, they will help build more resilient and sustainable next-generation data centers.
Conclusion
Solid-state transformers and aluminum hydroxide flame-retardant cables focus respectively on innovating energy conversion and safeguarding physical security. Their deep integration and application reflect the high level of responsibility modern data centers hold for life and asset safety while pursuing extreme efficiency. Together, they lay a solid and reliable physical foundation for the digital economy.
