American-style box-type substation 800kVA prefabricated box-type substation ZGS11 modular substation
Compact and Space-Efficient Design – By integrating the transformer, load switches, and fuses directly into the oil tank, the substation achieves a smaller overall structure, saving space and simplifying installation.
Safe and Reliable Operation – The fully insulated and sealed construction provides excellent protection, ensuring operational safety and long-term reliability.
Maintenance-Free and Easy to Operate – Designed for user convenience, the system requires little to no maintenance while remaining easy to operate in diverse settings.
Versatile Applications – Widely applicable in residential areas, industrial facilities, transportation hubs, and educational institutions, offering flexibility across multiple environments.
ZGS11 Modular Substation Overview
The American-style modular substation houses the transformer, high-voltage load switches, fuses, and other components within the transformer oil tank. Immersed in oil, the components are significantly smaller, resulting in a more compact structure and convenient and flexible installation. Its fully insulated and sealed structure ensures safety, reliability, ease of operation, and maintenance-free operation. It is widely used in residential areas, high-tech centers, factories, mines, airports, train stations, and schools.
Structural Features of American-Style Box-Type Substations
- Compact structure, small size, easy installation, and flexibility;
- Fully insulated, fully sealed structure, safe, reliable, maintenance-free, and reliable protection for personnel;
- Dual fuses on the high-voltage side: plug-in fuses with dual-sensitivity (temperature and current), and backup fuses with current-limiting fuses, reducing operating costs;
- The high-voltage incoming line utilizes a cable connector structure, fully insulated, safe, reliable, and easy to operate;
- Can be used in both ring networks and terminals, offering convenient conversion and improving power supply reliability;
- The transformers feature a three-phase, three-pole or three-phase, five-pole structure, with cores using stepped joints or wound cores for low noise, low losses, and strong short-circuit and overload resistance.
- Special vacuum drying and vacuum oiling processes are used.
- The box body can be designed with an anti-corrosion design and a special paint finish to meet the requirements of the operating environment. It offers "three-proof" features: condensation resistance, salt spray resistance, and mildew resistance, and can meet corrosion requirements in high-temperature and high-humidity environments.
Scope of Application
① Urban public power distribution systems: Increased transformer capacity is required in residential areas and busy streets when loads increase.
② Temporary power supply at construction sites: Where existing buildings require renovation or additional electrical equipment, this is also used for field operations and outdoor work sites, such as oil fields, mining operations, ports, terminals, and train stations.
