Box type substation ZGS□-12 Combined Container Substation (American Type) The ZGS-12 Combined Unit Substation (American Type) is a domestically produced American-type Container Substation introduced by our company. Serving as a crucial power supply unit in cable distribution networks, it integrates high-voltage control, protection, transformation, and distribution equipment into a complete prefabricated product. It finds wide applications in both urban and rural distribution networks. Our product positions the high-voltage load switch and high-voltage fuse in the transformer oil, featuring two structural forms: shared enclosure with the transformer or separate enclosures. It adopts a fully sealed structure and is equipped with components such as an oil temperature gauge, oil level gauge, pressure gauge, pressure release valve, and drain valve to monitor the transformer's operational status. This product is available in ring network type, terminal type, and dual power supply type. To better adapt to various application scenarios, our company has introduced plug-in dry-type fuses, where the fuse blowing does not affect the performance of the transformer oil. Depending on the complexity of low-voltage feed-out requirements, the ZGS-12 model is offered in three shell forms: standard, reinforced, and comprehensive, providing users with greater flexibility and cost-effectiveness during selection.

Structural Features

Compact structure, small size, only about 1/3 to 1/5 of the same capacity domestic European-style container substation, significantly reducing the footprint.

● Fully sealed, fully insulated structure, no need for insulation distance, reliably protecting personal safety

● High-voltage connections can be used for both ring networks and terminals, providing flexible power supply options with high reliability

● The transformer exhibits outstanding performance with low losses, low noise, and low temperature rise. It also has strong overload capacity, short-circuit resistance, and impact resistance. It meets various low-voltage feed-out requirements and can be selected according to specific plans or designed based on individual preferences.

● The cable connector comes in two types: a 200A elbow plug and a 600A T-shaped fixed cable connector. Both can be equipped with fully insulated zinc oxide surge arresters. The 200A cable connector allows for plugging when on load and can also serve as an isolating switch
