400kVA Oil Immersed Transformer

The 400kVA Oil Immersed Transformer is a reliable and efficient power distribution solution designed for medium and low voltage electrical networks. It is widely used in industrial facilities, commercial buildings, renewable energy systems, utility distribution networks, and infrastructure projects where stable and continuous power supply is required.

Designed with advanced transformer manufacturing technology, the 400kVA oil immersed transformer combines high-quality materials, optimized electrical design, and strict production control to achieve excellent performance, low operating losses, and long service life.

The transformer adopts a high-grade grain-oriented silicon steel core with a low-loss magnetic circuit design, effectively reducing no-load losses and improving energy efficiency. The carefully designed core structure also helps minimize noise levels and enhance operational stability during long-term operation.

The winding system uses high-conductivity copper or aluminum conductors with high mechanical strength and excellent electrical conductivity. The optimized winding structure improves short-circuit resistance, ensures uniform current distribution, and provides reliable performance under different load conditions.

The transformer uses high-quality insulating oil as the main insulation and cooling medium. The oil circulation system efficiently transfers heat generated during operation, maintaining safe temperature levels and improving transformer reliability. The sealed oil tank design helps prevent moisture, dust, and external environmental factors from affecting internal components.

The 400kVA oil immersed transformer is designed for various installation environments, including outdoor substations, industrial power systems, solar power plants, and utility distribution applications. With a strong structure, excellent thermal performance, and flexible configuration options, it can operate reliably in different climate conditions, including high-temperature and harsh outdoor environments.

Before shipment, every transformer undergoes strict quality inspections and complete routine tests, including winding resistance test, voltage ratio test, insulation resistance test, no-load loss test, load loss test, dielectric strength test, and leakage inspection. These procedures ensure that each unit meets international quality requirements and provides safe, stable, and long-lasting operation.
