Application

Data centers are the backbone of the digital economy. Every second of downtime translates into massive revenue loss and reputational damage. At the heart of a data center’s electrical infrastructure lies the power distribution transformer – a component often overlooked but absolutely critical for reliability, efficiency, and safety. At Shandong Kerui Transformer Co., Ltd. , we deliver state-of-the-art dry-type transformers specifically engineered for the unique demands of modern data centers (Tier III / Tier IV).

Why Data Centers Demand Specialized Transformers
Unlike conventional buildings, data centers require transformers that excel in:

• Ultra-low noise – IT staff work near server rooms; noise regulations are strict.

• High energy efficiency – Reducing electrical losses directly lowers PUE (Power Usage Effectiveness).

• Fire safety – No flammable oil allowed; dry-type transformers are mandatory.

• Compact footprint – Space in data centers is at a premium.

• Low harmonic distortion & high short-circuit withstand – Protecting sensitive servers and UPS systems.

• 24/7 continuous operation – Maximum reliability with minimal maintenance.

Our Transformer Products for Data Centers

1. SCB Series – Epoxy Resin Cast Dry-Type Transformers
   – The first choice for indoor data center substations.
   – Fire-resistant, self-extinguishing, zero leakage risk.
   – Ultra-low noise design (≤42 dB).
   – Available in energy efficiency grades: SCB14 (Level 2) and SCB18 (Level 1).
   – Voltage range: 6KV, 10KV, 20KV, 35KV down to 0.4KV.

2. SGB Series – Non-Encapsulated Dry-Type Transformers (Class H Insulation)
   – Also known as open-type or gas-insulated dry-type.
   – Excellent overload capacity for unpredictable IT load surges.
   – Suitable for high ambient temperature environments.

3. Low-Voltage Isolation Transformers
   – For critical IT equipment, UPS bypass, and power conditioning.
   – Eliminate ground loops and provide galvanic isolation.

Key Advantages of Kerui Transformers for Data Centers

• Ultra-High Energy Efficiency: Our Level 1 (SCB18) and Level 2 (SCB14) transformers dramatically reduce no-load and load losses. For a 2MW data center, upgrading from SCB12 to SCB18 can save thousands of kWh annually, directly improving PUE by 0.01–0.03.

• Silent Operation: Special core stacking and vibration damping technology ensure noise levels as low as 40–42 dB, meeting the strictest requirements for IT rooms.

• Fire Safety: Class F1 fire performance – no toxic smoke, no fire propagation. Fully compliant with NFPA, IEC, and local building codes.

• High Short-Circuit Withstand: Robust winding design withstands sudden current surges without deformation.

• Compact & Clean: Smaller footprint and clean appearance fit easily into electrical rooms, skids, or containerized substations.

• Low Partial Discharge: Epoxy resin vacuum casting ensures long insulation life and high reliability.

Typical Data Center Applications

• Utility feed step-down: 35KV / 10KV to 0.4KV for main distribution.

• UPS input/output isolation: Isolation transformers for harmonic filtering and grounding.

• Redundant transformer banks: N+1 or 2N configurations for Tier IV uptime.

• Containerized / modular data centers: Compact box substations or skid-mounted transformers.

Case Example
A Tier III data center in the Middle East (UAE) replaced their existing dry-type transformers with our SCB18 (Level 1) units. The result: measured no-load loss reduced by 28%, PUE improved from 1.42 to 1.38, and noise dropped from 58 dB to 43 dB, greatly improving operator comfort.
