  • Dry Type Transformer

    Dry-type transformer is a kind of transformer using air as cooling medium, mainly used for conversion and transmission of electric energy. Unlike oil-immersed transformers, the windings and core of a dry-type transformer are not immersed in oil, and are usually covered with resin or insulating material, which provides better insulation.

  • Oil Immersed Transformer

    Oil-immersed transformer is a transformer that uses transformer oil as a cooling medium, utilizing the principle of electromagnetic induction to convert high-voltage current to low-voltage current, or vice versa. Its basic components include primary side (high voltage side), secondary side (low voltage side), core and insulating oil.

  • Box Type Transformer

    Box-type substation is compact and occupies less land area compared to traditional substations, making it suitable for cities and areas with limited space. Convenient installation: As it is a factory prefabricated product, the box-type substation can be installed quickly, shortening the construction period and reducing the difficulty of construction.

  • Photovoltaic Transformers

    Photovoltaic transformers are key equipment in solar power generation systems. They are mainly used to boost the low-voltage AC power output by photovoltaic inverters to the voltage level required by the grid (such as 10kV, 35kV, etc.), ensuring that the power is efficiently integrated into the grid or used locally.

Expert Guide: How to Accurately Calculate Capacity for a Three-phase Transformer and Choose a Quality Manufacturer

In power engineering design, selecting the appropriate rated voltage and rated capacity is the core of ensuring safe grid operation. Many customers are often confused during the initial procurement phase about how to calculate the capacity of a Three-phase transformer based on actual loads. As a professional Three-phase transformer manufacturer, we recommend that the power factor and load factor must be considered during calculation. According to industry experience, the high-voltage side voltage should equal the grid voltage it connects to, while the low-voltage side voltage is typically 10% or 5% higher than the grid voltage. Oversizing leads to waste, while undersizing creates safety hazards; therefore, accurate calculation is the cornerstone of project success.
