Product Overview
  • Core Advantages & Application Scenarios

    The equipment has reliable moisture and dust resistance, capable of handling the humid environment of southern China's plum rain season or small suburban factories with high dust levels. It can operate stably without additional protective devices, reducing initial investment costs. Its heat dissipation structure is optimized for medium-low load conditions, eliminating the need for frequent maintenance of heat dissipation components and further lowering operational and maintenance expenses. Therefore, it is more suitable for projects that have no excessive energy efficiency requirements and prioritize basic safety and cost control—such as power distribution upgrades in old communities, supporting power supply for small warehouses, and independent power distribution for street convenience stores—rather than being limited to conventional commercial or residential power distribution scenarios.
