The single-phase American-type pad-mounted transformer oil tank is the core pressure-bearing integrated enclosure of a single-phase combined transformer (single-phase American-type pad-mounted transformer). It features a fully sealed, oil-immersed shared-tank structure. Its core design feature is that the single-phase transformer active part and all high-voltage components, including the high-voltage load switch, fuse, and surge arrester, are immersed in the same insulating oil compartment. Only the low-voltage operating unit is separated into an independent compartment by a steel plate, resulting in an exceptionally compact overall design. Mainstream product capacities range from 5 kVA to 200 kVA, suitable for 10 kV/0.23 kV voltage ratings.

Key advantages include an exceptionally compact design, extremely high space utilization, full sealing and insulation, very low operation and maintenance costs, a comprehensive protection system, high operational reliability, efficient and flexible deployment, significant lifecycle cost advantages, and broad environmental adaptability.

Typical Application Scenarios

Power distribution for municipal public facilities: outdoor locations with concentrated single-phase loads, such as urban road lighting, traffic signals, and monitoring equipment. Units can be installed nearby to shorten the low-voltage power supply radius.

Power supply for dispersed urban and rural residences: single-phase residential power supply for scattered rural households and standalone suburban buildings, replacing long-distance low-voltage lines to reduce line losses and voltage deviation.

Small commercial and service businesses: low-capacity single-phase power applications such as street-front shops, small convenience stores, and newsstands, offering flexible deployment without occupying business space.

Temporary and emergency power supply: short-term power supply requirements for construction sites, exhibition events, and emergency repairs, allowing rapid installation and removal.

New energy supporting applications: grid-connection voltage step-up support for residential distributed photovoltaic systems and small single-phase energy storage systems. Nearby installation reduces cable losses.
