This type of electrical equipment uses insulating oil as its primary insulating medium and utilizes it for heat dissipation, and is widely used in power systems.
Key features include high safety, environmental friendliness, energy efficiency, ease of maintenance, and adaptability, making it suitable for locations with strict fire protection requirements or limited space.
With numerous advantages, including a small footprint, ease of operation, high application benefits, flexible configurations, and high operational safety, transformers are widely used in various fields and have become an indispensable component of power engineering construction.
Besides converting AC voltage, transformers have a variety of other applications, such as changing the frequency of power supplies, providing power for rectifiers, welding equipment, furnaces, and acting as voltage and current transformers. Because the operating conditions and load profiles of these transformers differ from those of standard transformers, calculations for these transformers cannot be performed using standard transformer calculation methods.
Zhejiang Baiyun Zhebian Electrical Equipment Co., Ltd., formerly Wolong Electric Group Zhejiang Transformer Co., Ltd., was founded in 2009. In July 2017, it was acquired and restructured by Guangzhou Baiyun Electrical Equipment Co., Ltd. (stock code: 603861).
