Medium-Low Voltage Prefabricated Substations

Core Functions and Composition

This module integrates the entire power chain—from input to distribution—and comprises the following key components:

Medium-Voltage Distribution Unit: Typically includes 10kV medium-voltage switchgear responsible for receiving and converting high-voltage power.

Transformation and Low-Voltage Unit: Includes transformers and low-voltage distribution cabinets to step down voltage to the 380V required by data centers and manage precise power distribution.

Emergency and Energy Storage Systems: Integrates UPS (Uninterruptible Power Supply), DC-UPS, and lithium-ion energy storage modules to ensure power continuity.

Auxiliary Monitoring Systems: Features built-in precision air conditioning, fire safety and security systems, environmental monitoring, and visualization management systems to ensure a safe and stable operating environment.

Core Advantages

Significantly Enhanced Deployment Efficiency: Reduces on-site workload by over 70%, compresses deployment time from months to days, and cuts on-site labor requirements by more than 60%.

Superior Safety and Reliability: Supports multiple redundancy configurations (such as 2N and N+1) to meet the power continuity requirements of high-tier data centers; prefabricated copper busbar connections reduce line losses by nearly 1%.

Convenient O&M: Core power modules support hot-swapping, enabling maintenance without system downtime, while the built-in intelligent monitoring system allows for remote monitoring of end-to-end power data.

Application Value

Compared to traditional on-site construction methods, the factory-prefabricated nature of these modules effectively avoids drawbacks such as weather-related delays and ambiguous accountability arising from multi-party cross-operations. Their standardized design ensures controllable construction schedules; on-site work is limited to hoisting and interface connections, thereby drastically improving the delivery efficiency and reliability of data center power infrastructure.
