Customization Optional
100kVA Oil Immersed Transformer
GNEE's three-phase oil-immersed transformers can be fully customized to meet your specific requirements.
The optional specifications of the 100kVA three-phase oil-immersed transformer include a variety of customized options to meet different application requirements. Customers can choose different voltage levels and load adjustment devices, such as tap switches with load or no load adjustment, to ensure accurate output of voltage. In addition, the transformer can be equipped with a temperature monitoring system, an oil level monitoring device, and a pressure relief device to enhance safety and real-time monitoring. In order to improve the durability of the equipment, users can also choose anti-corrosion coating or stainless steel casing, which is suitable for use in harsh environments.
With these optional configurations, the 100kVA three-phase oil-immersed transformer can better adapt to different working environments and operating conditions.
