AMERICAN TYPE Compact Substation

American type prefabricated box substation is a compact, skid-mounted, fully integrated outdoor power distribution equipment designed according to ANSI and IEEE American standards. Different from European box substations, it adopts an integrated compact structure with transformer, high-voltage fuse, load switch and low-voltage distribution unit highly integrated in one sealed box. It features small footprint, simple structure, convenient installation and strong overload capacity, which is the mainstream power distribution equipment for North America, South America and overseas American-standard power grid projects.

FAQ

Q: What standards does your American box substation comply with?

Our products strictly comply with IEEE, ANSI, NEMA American standards and IEC international standards, fully adapting to North American, South American and other American-standard power grid projects.

Q: What is the difference between American type and European type box substation?

American box substation is highly integrated with smaller size, simpler structure and lower maintenance cost, adopting fuse protection mode, which is more suitable for American-standard power grids; European type adopts independent three-room structure with higher safety margin, more suitable for European and Asian standard projects.

Q: Can you customize voltage, frequency and capacity for American local projects?

Yes. We support full customization of 60Hz frequency, American standard voltage level, capacity, protection mode and box color to meet different regional project requirements.

Q: Is the equipment suitable for coastal high salt spray and high temperature areas?

Definitely yes. The box adopts heavy-duty anti-corrosion and fully sealed waterproof design, with strong salt spray resistance and weather resistance, which can operate stably in harsh coastal, high temperature and rainy environments.

Q: How long is the installation and commissioning cycle?

All equipment is fully pre-assembled and pre-debugged in the factory. On-site installation only needs foundation placement and cable connection, which can complete power transmission within 1 day, saving a lot of construction time.

Q: Do you have export experience for American standard box substations?

We have rich export experience for American-standard power equipment, familiar with local project acceptance rules and export customs clearance procedures, and can provide complete certification documents and remote technical support.

Q: What is your warranty policy?

We provide 2-year free warranty and lifelong technical support. Any quality problems during the warranty period can be solved with free replacement and after-sales service.
