The ZGS type combined transformer originated in the United States and is widely used in the American power distribution system. It optimally combines the transformer body, high and low voltage electrical components, with high-voltage load switches and fuses placed in transformer oil. The oil tank is fully sealed and equipped with components such as an oil temperature gauge to monitor operation. Its volume is only 1/3 - 1/5 of that of European-style box-type transformers with the same capacity, featuring advantages like small footprint, easy installation and reliable operation, and is suitable for residential quarters, commercial centers and other places.

◆ Compact structure, integrating transformer and high-low voltage components, with a volume only 1/3-1/5 of European-style box-type transformers of the same capacity, occupying extremely small space.

◆ Fully sealed oil tank design with oil-immersed high-voltage components, dustproof and moisture-proof, adaptable to complex environments and reliable in operation.

◆ Easy to install, no need for infrastructure, can be directly installed on the ground or poles, shortening the construction period.

◆ Equipped with complete monitoring components such as oil temperature gauges to keep track of operating status in real time, with simple maintenance.

◆ Strong adaptability, widely used in urban and rural power grids, residential quarters, industrial parks and other scenarios.
