-
Structural Characteristics: The transformer, high-voltage load switch, and fuses are all sealed within the same oil tank, resulting in a very compact size.
Advantages & Disadvantages: Compact structure, low cost, and small footprint. However, overall heat dissipation is slightly poorer, and because components share a common tank, an internal fault may affect all equipment. There is no separate transformer compartment.
Application Scenarios: Residential communities, street lighting, temporary power supply, and other locations with high space requirements and relatively stable loads.No.
