three-phase transformer

1. Product Introduction

Oil-immersed distribution transformer series 10 kV. This product integrates optimized magnetic circuit design, high-efficiency materials, and fully sealed structural technology, achieving triple optimization in reducing load, load loss, and operational noise. It combines exceptional safety, reliability, and an exceptionally long service life.

This product is specifically designed to meet the energy-saving and consumption-reduction requirements of power grids in the context of 'dual carbon', applicable to 10 kV distribution systems at all levels. It serves as the core power distribution equipment for smart city construction, national key projects, high-end industrial parks, and facilities with strict demands for energy consumption and noise levels.

2. Technical specifications (customizable)

• Energy efficiency class: high efficiency and energy savingtransformer• Connection group: Dyn11 • Cooling method: ONAN (oil-immersed self-cooling) • Rated power: 10KVA-5000KVA • Impedance voltage: 4% (standard configuration) • Insulation class: Class A • Operating environment: -25°C to +55°C, suitable for harsh outdoor conditions, including high humidity, salt spray, and dust.

 3. Key features

Impact resistance and high reliability: The coil uses high-strength oxygen-free copper conductors and vacuum casting/impregnation technology, ensuring exceptional mechanical strength and excellent resistance to sudden short circuits. It effectively withstands sharp voltage fluctuations and load surges in the power grid, ensuring safe and stable operation with an extremely low failure rate.

Long service life and excellent weather resistance: high-quality thermal insulation oil combined with heat-resistant insulation material systems, with a service life exceeding 30 years. The surface of the oil tank is treated with fine sandblasting and three-proof paint, demonstrating exceptional resistance to corrosion and aging, making it ideal for highly corrosive environments such as open and coastal areas.

4. Application scenarios

• Elite commercial and residential buildings: super high-rise office towers, large shopping malls, tertiary Class A hospitals, university towns, and cultural tourism complexes, designed to simultaneously reduce noise and ensure high reliability of power supply.

• High-energy-intensive/technologically costly enterprises: chemical plants, new energy industrial parks, data centers, and high-precision manufacturing facilities achieving core cost advantages through extreme energy efficiency.

• Infrastructure and special power supply: Power supply for highway service areas, railway stations, seawater desalination plants, and base stations in remote areas demonstrates its excellent weather resistance.
