Technical Differences

Insulation and Cooling

Insulation and cooling methods play a crucial role in transformer performance and safety. Ouxu Electric’s dry type amorphous alloy transformer uses solid insulation, such as epoxy resin or cast resin, and relies on air or forced-air flow for cooling. This design eliminates the need for oil, making it safer for indoor environments and areas with strict fire protection requirements. In contrast, the oil immersed tap changer transformer uses insulating oil both as a coolant and as an insulator. The oil circulates inside the transformer, carrying heat away from the core and windings, which allows for efficient cooling even under heavy loads.

Note: Ouxu Electric’s SCBH15-30-2500/10 dry type amorphous alloy transformer offers high safety and minimal maintenance, while the Factory 10kV oil immersed transformer excels in outdoor cooling and voltage stability.

Design and Efficiency

Ouxu Electric’s commitment to innovation is clear in the design of both transformer types. The dry type transformer features an amorphous alloy core, which reduces no-load loss by up to 60% compared to traditional models. This core material, combined with advanced winding technology, ensures high energy efficiency and quiet operation. The oil immersed tap changer transformer, on the other hand, uses a robust core and winding structure with on-load tap changing capability. This allows for precise voltage regulation and stable performance, even when power demands fluctuate.

Ouxu Electric invests heavily in research and development, holding dozens of patents for transformer technology. Their engineers have developed solutions that improve energy savings, extend service life, and enhance safety. These achievements help customers reduce operational costs and meet global energy standards.
