Product introduction
The ZGS-H(Z) combined substation (also known as the American-style packaged substation) is a product where the transformer core, high-voltage load switch, protective fuses and other equipment are designed in a unified way and placed in the same sealed oil tank. It is equipped with a complete set of operation inspection instruments, such as pressure gauges, pressure relief valves, oil level gauges, oil temperature gauges, etc.The American-style packaged substation has outstanding performances such as reliable power supply, reasonable structure, rapid, flexible and convenient installation, small size, and low cost. It can be used both outdoors and indoors, and is widely applied in various places, including industrial parks, residential communities, commercial centers, high-rise buildings, etc.

Product features
Our ZGS - H(Z) combined substation features a fully sealed and insulated structure, eliminating the need for insulation distance and ensuring reliable protection of personal safety. It is compact in size, only about one - third the volume of domestic box - type substations of the same capacity. It can be used in both ring - main and terminal networks with convenient conversion, enhancing power supply flexibility. With low losses equivalent to domestic transformers of the same type, we can provide different series of combined transformers with varying loss levels and amorphous alloy core series according to customer needs. The cable joint can handle a 200A load current and can be used as a load switch in emergencies while also having the characteristics of a disconnector for easy and flexible operation. Equipped with double - fuse protection, it ensures reliable operation. The enclosure, with its anti - corrosion design and special painting treatment, is widely applicable to harsh environments like highly polluted areas with frequent storms.
