Project Background
With rapid business growth, a large e-commerce enterprise faced increasing pressure on its existing data center infrastructure. To support expanding data processing and storage demands, the company launched a new data center project with a total construction area of approximately 5,000 square meters and a deployment scale of nearly 5,000 servers. The facility supports critical systems such as the e-commerce trading platform, logistics management system, and customer service applications, all of which require continuous, uninterrupted operation.
In high-traffic scenarios such as major online promotions, even brief power fluctuations or outages can lead to transaction failures, order losses, and significant financial and reputational impact. As a result, the new data center imposed extremely high requirements on power supply continuity, stability, and safety, making the UPS room a core component of the entire infrastructure.
UPS Room Power Solution Design
To ensure a highly reliable power supply for the data center, the project adopted a robust electrical architecture combining dry-type transformers and MNS low-voltage withdrawable switchgear. The overall design focuses on redundancy, safety, energy efficiency, and ease of operation and maintenance.
Dry-Type Transformer Selection
Based on detailed load calculation and future capacity planning, two SCB10 2500kVA dry-type transformers were selected. Each transformer features a rated capacity of 2500kVA, three-phase configuration, 10kV primary voltage, and 0.4kV secondary voltage, ensuring seamless integration with the utility grid and downstream equipment.
These SCB10 transformers offer excellent energy efficiency, with no-load losses as low as 1.4kW and load losses of only 13.9kW at 75°C. This significantly reduces long-term operating costs while supporting sustainable data center operation. The oil-free dry-type design eliminates leakage and fire risks associated with oil-filled transformers, fully meeting stringent data center fire safety and environmental requirements.
MNS Low-Voltage Withdrawable Switchgear Configuration
For low-voltage power distribution, the project deployed a 10-panel MNS series low-voltage withdrawable switchgear system. With a maximum rated current of up to 6300A, the MNS switchgear easily meets the power distribution demands of large-scale data center equipment and UPS systems.
The switchgear offers a high short-circuit breaking capacity of 150kA, ensuring effective protection against fault currents and enhancing overall system safety. Its modular withdrawable design simplifies installation, inspection, and maintenance, minimizing downtime during equipment servicing.
In addition, the MNS switchgear is equipped with an intelligent monitoring module capable of real-time measurement of voltage, current, power, and other key parameters. Through standard communication interfaces, operational data can be transmitted to the data center monitoring system, enabling remote supervision, fault diagnosis, and energy management.
Project Value and Operational Benefits
The combination of SCB10 dry-type transformers and MNS low-voltage withdrawable switchgear provides a highly reliable and flexible power distribution solution for the new data center UPS room. The system ensures stable power delivery, reduces operational risks, improves maintenance efficiency, and supports future capacity expansion.
This project demonstrates the suitability of MNS low-voltage switchgear solutions for modern data centers that demand high reliability, strong short-circuit protection, intelligent monitoring, and long-term operational efficiency.
The successful implementation of the MNS low-voltage withdrawable switchgear in this new data center UPS room project highlights the critical role of high-quality electrical equipment in supporting mission-critical digital infrastructure. As data centers continue to expand in scale and complexity, proven power distribution solutions like MNS switchgear and dry-type transformers will remain essential to ensuring safe, stable, and uninterrupted operation.
