Single-phase cylindrical oil-immersed transformer 25kVA 50kVA - China Transformer
Model Definition

Features
² Cylindrical design: The cylindrical outer shell provides strong wind resistance and excellent heat dissipation.
² High efficiency and energy saving, extending transformer lifespan.
² Multiple protection features: While ensuring efficient and stable output in harsh environments, it also provides protection against overheating, overvoltage, overcurrent, overload.
² Compact structure, small size, and light weight, facilitating installation and maintenance.
² Suitable for outdoor installation, requiring minimal infrastructure investment, and providing continuous and stable power supply in any environment.
Range of application
Suitable for a variety of complex installation scenarios, such as underground power distribution rooms in central urban areas, basements in commercial complexes, underground power distribution areas in traffic tunnels, and supporting power distribution facilities in outdoor, scenic spots, subway stations, underground parking lots, etc. These scenarios generally have high requirements for equipment operation noise, space occupation and sealing protection.
