Main Application Areas1. Commercial and Public Facility Power Supply: Provides reliable three-phase power to shopping malls, office buildings, schools, hospitals, and government buildings.
2. Light Industry and Manufacturing: Suitable for small factories, processing workshops, warehouses, and assembly lines.
3. Medium- and High-Density Residential Areas: Provides centralized power supply solutions for apartment buildings, residential communities, and townhouse complexes.
4. Rural Electrification: Serves large farms, irrigation pumping stations, livestock facilities, and agricultural product processing centers.
5. Renewable Energy Connection Points: Serves as grid connection points for small photovoltaic power plants and wind farms, connecting distributed generation to the 12.47kV distribution network.

Core Product Advantages1. Product design is fully compatible with North American and US power grid standards, ensuring immediate use without additional adaptation.
2. Product meets UL/CUL certification and comes with a complete IEEE standard test report, facilitating smooth project approval and acceptance.
3. Pole-mounted installation eliminates the need for a distribution room and concrete foundation, saving on civil engineering costs.
4. Installation close to load centers significantly shortens the low-voltage power supply radius, reduces line losses, and improves overall system energy efficiency.
