Weekly Product Spotlight: ZGS11-12 Combination American Prefabricated Substation

Product Overview
The ZGS11-12, often called the "American-style compact substation," is an integrated power distribution solution that combines high-voltage switching equipment, the transformer, and low-voltage functionality within a single sealed oil tank. Known for its small footprint, fully insulated design, and maintenance-free operation, it is an ideal choice for modern distribution networks.
Core Structure & Design
Its core design is the "integrated tank" structure. The high-voltage load switch, fuses, and transformer core are all sealed within a single oil-filled tank, making the structure extremely compact—about one-third the size of traditional European-style substations. The low-voltage compartment is independently separated for easy operation and maintenance. The fully insulated and sealed design eliminates the risk of exposed live parts and effectively protects against dust, moisture, and condensation, with an protection rating of IP43.
Technical Parameter Highlights
According to the provided technical parameters, key specs for the ZGS11-12 include:
Rated Voltage: 10/4 kV (High-Voltage/Low-Voltage)
Rated Capacity: 50-1600 kVA (Wide range)
Noise Level: < 50 dB (Very quiet operation)
Protection Level: IP43 (Good dust and water splash protection)
Ambient Temperature: -35°C to +40°C (Suitable for harsh climates)
Functions & Advantages
Flexible Power Supply: Supports ring-network, dual-power, or terminal supply modes, enhancing power supply reliability.
Comprehensive Protection: Uses plug-in and backup fuses for full-range protection, with capabilities against lightning, overload, and short circuits.
Cost-Effective: Small size reduces land use, and easy installation cuts civil works and setup time/costs. Maintenance-free design lowers lifecycle costs.
Smart Options: Can be equipped with remote monitoring, energy metering, and reactive power compensation for smart grid operation.
Application Scenarios
The ZGS11-12 is widely used in:
Urban Distribution: Residential areas, commercial centers, parks, airports, metro stations.
Industrial Sector: Industrial parks, factories, and mines.
New Energy: Photovoltaic power stations, wind farms (special models like ZGS11-Z.G available).
Temporary Supply: Construction sites, large event venues.

Conclusion:
With its integrated design, excellent environmental adaptability, flexible application, and robust protection, the ZGS11-12 Combination American Prefabricated Substation holds a significant position in the compact power distribution sector. It is an ideal solution for enhancing the reliability, efficiency, and aesthetics of distribution networks, perfectly meeting the needs of modern urban and new energy development.
