A container substation is an integrated, modular, prefabricated power distribution unit that combines transformers, high and low voltage cabinets, monitoring and protection systems, and more. Once fully assembled and tested at the factory, it’s shipped as a complete unit. Container substations don’t need complicated construction work; they can be put into operation on-site with simple connections, making them suitable for all kinds of outdoor, temporary, and renewable energy power supply scenarios.
 
Ⅰ. Features of Container Substations
Container substations use a standardized container cabinet integrated design. They are fully sealed and well-protected, able to withstand harsh environments like wind, rain, dust, and extreme temperatures. These substations are highly modular, with flexible configurations, making them easy to transport and relocate. They are mostly prefabricated in the factory, which greatly reduces on-site work, speeds up construction, takes up less space, and ensures strong overall stability.

Ⅳ. Daily Maintenance Tips for Container Substations
1. Regularly check the container substation's door locks and sealing strips to prevent rainwater and dust from entering the equipment.
2. Every month, inspect the high and low voltage cabinets and terminal blocks for any looseness, overheating, or oxidation.
3. Check the cooling fans and dehumidification equipment regularly to make sure ventilation, heat dissipation, and moisture-proof systems are working properly.
4. Periodically clean dust and debris inside the container substation to keep the equipment clean and dry.
5. Check the smart monitoring and protection instrument data to ensure parameters are normal and there are no fault alarms.
6. After the rainy season or heavy wind and dust weather, promptly inspect the container’s exterior and grounding devices to make sure they’re intact.
7. Never operate with overloads, and regularly test insulation performance to eliminate any electrical safety risks.
