American-style substation

The ZGS11-□-12/0.4 series prefabricated American-style pad-mounted substation, commonly referred to as an “American substation,” “American-type pad-mounted substation,” or “combined transformer,” is an outdoor pad-mounted substation in which the transformer core, high-voltage load switch, fuses, and other components are all housed within a single transformer oil tank, while the low-voltage compartment is enclosed in a single, integral outdoor cabinet that is further divided into metering, incoming line, outgoing line, and capacitor compartments, all compactly assembled together.

　　 Selling Points and Advantages

　　1. Compact structure and small footprint—only about 1/3 to 1.5 times that of a domestically produced European-style pad-mounted substation of the same capacity—significantly reducing the required land area.

　　2. Fully sealed and fully insulated design eliminates the need for clearance distances, providing reliable protection for personal safety.

　　3. High-voltage wiring can be used for both ring networks and terminal applications, offering flexible power supply configurations and high reliability.

　　4. Outstanding transformer performance: low losses, low noise, and low temperature rise; strong overload capability, excellent short-circuit resistance, and high impact withstand capability.

　　5. Meets various low-voltage feeder requirements; options can be selected based on the scheme, or a custom design can be developed.

　　6. The cable terminations are available in two types: a 200 A elbow-type plug and a 600 A “T”-type fixed cable connector. Both can be equipped with fully insulated zinc oxide surge arresters. The 200 A cable termination allows for load-break connection and disconnection and can also function as an isolating switch.
