Insulation and Cooling: Transformer oil is used as both an insulating material and a cooling medium for the internal windings and core of the transformer, effectively dissipating heat.

Structural Components: Mainly includes the core, high and low voltage windings, oil tank, radiator, insulating bushings, etc.

Core: Typically made of high-quality cold-rolled silicon steel sheets to reduce hysteresis and eddy current losses.

Windings: Winded from insulated conductors (such as enameled wire), with the low-voltage winding usually on the outside.

Oil Tank: A steel oil tank to house the core, windings, and insulating oil, and equipped with accessories such as an oil level gauge and thermometer.

Power Systems: Used in remote areas or special situations where single-phase power supply is unavailable, to convert high-voltage electricity to a voltage suitable for user use.

Industrial Sector: Provides power to industrial equipment requiring single-phase high-voltage power, such as small electric furnaces or single-phase motors.

Testing and Inspection: Used as a high-voltage supply device in electrical equipment testing and inspection, for insulation withstand voltage tests, etc.

Rural Power Grid Upgrading: Suitable for power grid upgrading projects in rural and mountainous areas, reducing line losses and improving power supply quality.

High Energy Efficiency: Compared to traditional single-phase transformers, certain designs (such as high-efficiency energy-saving wound cores) can achieve higher energy efficiency.

High Cost-Effectiveness: Pole-mounted installation reduces infrastructure investment, making it particularly suitable for areas with dispersed power supply.

High Reliability: Utilizing a fully sealed structure, it boasts strong overload capacity, high operational reliability, and simple maintenance.
