The three-phase American-style box-type transformer tank is the core pressure-bearing integrated carrier of a three-phase combined transformer (American-style pad-mounted transformer). It is a fully sealed oil-immersed tank, featuring a design in which the transformer core and windings, high-voltage load switch, fuse, lightning arrester, and other high-voltage components are all immersed in insulating oil within the same tank. Only the low-voltage distribution unit is separated into an independent compartment by a steel plate, resulting in a highly integrated and compact overall structure. The product is mainly suitable for the 10 kV voltage class, with capacities ranging from 50 kVA to 3000 kVA.

Its key advantages include an extremely high level of integration, significant space-saving benefits, full sealing and insulation, safe maintenance-free operation, a comprehensive protection system, high operational reliability, efficient deployment, low construction costs, strong environmental adaptability, and broad application coverage.

Typical Application Scenarios

Industrial settings such as factories, mines, and oilfields: Offers strong reliability under heavy and fluctuating loads, adapts to harsh plant environments, requires no dedicated personnel for operation and maintenance, and meets the terminal power distribution needs of industrial and mining enterprises.

Transportation hubs such as ports, airports, and highways: Requires a small footprint and offers flexible deployment. It can be installed close to load centers to reduce low-voltage line losses, making it suitable for linear and distributed transportation power distribution applications.

Urban public buildings and residential communities: Its compact structure can be integrated into green belts and underground facilities without occupying core building space. The fully insulated design ensures personnel safety and meets municipal, commercial, and residential power distribution requirements.

Temporary construction and emergency power supply scenarios: Convenient to install and relocate, enabling the rapid setup and removal of power distribution points, and suitable for short-term power supply needs at construction sites and for emergency support.

New energy supporting applications: Suitable for voltage step-up and grid connection in distributed photovoltaic and small wind power applications. It can be installed close to power generation units to reduce cable costs and meet unattended operation and maintenance requirements.
