As a highly adaptable Outdoor Mobile Prefabricated Substation, it boasts core advantages of small size, easy installation, low noise, low loss, full protection, convenient maintenance and high cost performance. It is not only a dedicated temporary power supply equipment for various construction sites, but also widely suitable for new industrial parks, urban green belts, stations, docks, hotels, airports and other fixed and mobile power distribution scenarios. The integrated structural design of the compact Prefabricated Substation makes it easy to transport and deploy, and the flexible configuration of electrical components further enhances its compatibility with different power supply demands of various scenarios.
Use environment
The compact Prefabricated Substation and Outdoor Mobile Prefabricated Substation both comply with unified strict environmental adaptation standards, with the following applicable working conditions:
- Altitude: Suitable for installation and operation at an altitude not exceeding 1000m above sea level, ensuring stable performance under standard atmospheric pressure conditions.
- Ambient Temperature: The upper limit of ambient air temperature is 40°C, and the lower limit is -25°C, adapting to seasonal temperature changes in most regions and meeting the outdoor operation requirements of the Outdoor Mobile Prefabricated Substation.
- Wind Speed: The indoor wind speed does not exceed 35m/s, and the structural design can resist the impact of normal wind speed, ensuring the structural stability of the compact Prefabricated Substation.
- Relative Humidity: The daily average relative humidity is not more than 95% (at 25°C), and the monthly average is not more than 90% (at 25°C), with excellent moisture-proof performance to avoid electrical faults caused by high humidity.
- Vibration & Impact: No frequent violent vibration and impact at the installation site, protecting the internal precision components of the Outdoor Mobile Prefabricated Substation from damage.
- Site Requirements: No flooding, explosion hazards, serious contamination and chemical corrosion at the installation site; the corrosion-resistant structural design further reduces the impact of mild environmental pollution on the compact Prefabricated Substation.
Quality assurance

Additional Application Scenario
Temporary Power Supply for Large-Scale Cultural and Sports Events
- The Outdoor Mobile Prefabricated Substation is the core temporary power supply equipment for large-scale cultural and sports events such as stadium competitions, outdoor art festivals and urban square activities, and the compact Prefabricated Substation is the optimal matching choice for its auxiliary power supply system. Large-scale cultural and sports events have the characteristics of short holding time, temporary power supply demand, dense electrical load and diverse power consumption equipment (lighting, sound, stage machinery, security monitoring, etc.), and the Outdoor Mobile Prefabricated Substation’s mobile performance enables quick transportation and on-site deployment, completing the power supply commissioning in a short time to meet the urgent power demand of the event site.
- The compact Prefabricated Substation with small size and flexible configuration can be flexibly installed in the auxiliary area of the event site, providing targeted power supply for scattered load points such as security checkpoints and temporary service areas. Both the Outdoor Mobile Prefabricated Substation and compact Prefabricated Substation have the advantages of low noise and full protection, which not only avoid noise interference to the event site, but also eliminate electrical safety risks such as short circuit and overcurrent, ensuring the continuous and stable operation of event power supply equipment. After the event, the Outdoor Mobile Prefabricated Substation can be quickly disassembled and transported to the next application site, and the compact Prefabricated Substation is easy to store and reuse, realizing the efficient utilization of equipment, and is the ideal temporary power distribution solution for various large-scale temporary activities.
