Project Background & Client Requirements
Power Supply Characteristics of the Cold Chain Logistics Industry: Frozen food bases have extremely high requirements for power supply reliability. Any power interruption to the refrigeration systems can lead to goods spoilage and significant economic losses. For a large-scale frozen food base with an annual capacity of 240,000 tons, its power supply system necessitates exceptionally high reliability, stability, and intelligent monitoring capabilities.
Specific Environmental Requirements of the Frozen Base: The internal environment of the base is characterized by low temperatures and high humidity. Furthermore, the frequent starting and stopping of refrigeration equipment places higher demands on the environmental adaptability and impact resistance of the power supply equipment. The client required a compact substation solution capable of adapting to the cold chain environment, featuring comprehensive protection functions, and supporting remote monitoring.
SH Power’s Solution
Addressing the specific needs of the frozen food base, SH Power provided a customized European-style compact substation solution:
