Step-down power transformer is a device used to reduce the voltage from the input power source to a lower level, typically used in electronic devices to match the required voltage.
Most step-down transformers use ‌EI-core‌ (E-shaped iron core), which is more common in industrial applications. Toroidal core transformers are also available, offering higher efficiency and lower noise. ‌

Service Voltage: 480V-380V                                                                     Rated Capacity: 700kVA 750kVA

Step-down power transformer is widely used in power distribution, electronics, lighting, rectifiers, audio systems, and uninterruptible power supplies (UPS). Customization is possible to match specific requirements. ‌
Standard models support 50/60Hz power frequency, while high-frequency designs can operate up to MHz range for specialized applications. ‌

Advantages of oil immersed transformers：

1.Strong adaptability
Suitable for complex environments such as high temperature, low temperature, and humidity, and has the ability to resist short circuits and withstand the impact of short circuit currents.

2.Efficiency
The efficiency of an 11kV three-phase oil immersed transformer can exceed 99%, which can meet the European 2015/2014/548/EC ecodesign Tier 2 energy efficiency regulations.
3.Maintenance free
IP65 protection level, dustproof and moisture-proof, maintenance free, designed for a lifespan of over 25 years.
