Reliable Switchgear, Package Substations & Transformers by YUGUANG

A stable and well-designed Electrical Distribution System in a Data Center is essential for ensuring uninterrupted operation, protecting critical IT infrastructure, and supporting long-term scalability. As data centers continue to grow in capacity and complexity, power distribution systems must deliver high reliability, redundancy, efficiency, and safety.

YUGUANG provides integrated electrical distribution solutions for data centers, supplying medium voltage switchgear, package substations, power transformers, and low voltage distribution panels engineered for continuous, mission-critical operation.

Power Architecture of a Modern Data Center

A typical data center electrical distribution system is designed to receive power from the utility grid or on-site generation and deliver stable power to IT and mechanical loads through multiple protection and conversion stages.

The standard power flow includes:

• Utility or on-site power source

• Medium voltage (MV) switchgear

• Transformer or package substation

• Low voltage (LV) switchgear

• UPS systems, PDUs, and IT equipment

Each stage is carefully coordinated to ensure fault isolation, operational safety, and uninterrupted power delivery.

Medium Voltage Switchgear for Data Center Applications

Medium voltage switchgear is the first critical control and protection layer in the data center power system. It manages incoming power, isolates faults, and distributes electricity to transformers or package substations.

YUGUANG MV switchgear is designed for:

• High short-circuit withstand capability

• Secure interlocking and protection systems

• Compact layouts suitable for indoor substations

• Stable performance under continuous load conditions

Common voltage levels include 6.6kV, 10kV / 11kV, 20kV, and 33kV, making the system adaptable to different grid standards worldwide.

Power Transformers for Continuous and High-Density Loads

Transformers are responsible for stepping down medium voltage to low voltage required by data center loads. Due to 24/7 operation and high power density, transformer performance directly affects energy efficiency and system reliability.

YUGUANG supplies oil-immersed and dry-type transformers optimized for data center applications, offering:

• Low no-load and load losses

• Excellent thermal stability

• Strong overload capability

• Long service life with minimal maintenance

Transformer capacities typically range from 1000 kVA to 2500 kVA, depending on data center size and redundancy requirements.

Package Substations for Modular and Fast-Track Projects

A package substation (also known as a compact or skid-mounted substation) integrates MV switchgear, transformer, and LV panel into a single factory-assembled unit.

For data centers, package substations provide clear advantages:

• Reduced on-site installation time

• Lower civil construction requirements

• Consistent factory quality and testing

• Modular design for phased expansion

YUGUANG package substations are widely used in prefabricated, modular, and edge data center projects, where speed and reliability are critical.

Low Voltage Switchgear and Power Distribution

After voltage transformation, power is distributed through low voltage switchgear and panels to UPS systems, cooling equipment, and auxiliary loads.

These LV systems are designed to handle high current levels safely while supporting:

• Load segregation for redundancy

• Easy maintenance and monitoring

• Long-term stable operation

Proper coordination between MV, transformer, and LV equipment ensures a balanced and efficient electrical distribution system.

Redundancy and Reliability Design

Data centers commonly adopt N+1, 2N, or 2N+1 redundancy architectures to achieve high availability. Electrical equipment must support:

• Dual incoming feeders

• Multiple transformers

• Independent switchgear sections

• Fault isolation without service interruption

YUGUANG solutions are engineered to integrate seamlessly into redundant power architectures, helping operators minimize downtime risk.
