Safe and Efficient Transformer for Modern Substation Systems

        Product Introduction：     The YB-12/0.4 prefabricated substation is a domestically manufactured American-style box substation. As an important power supply unit in cable-type distribution networks, it is a complete prefabricated assembly integrating high-voltage control, protection, voltage transformation and power distribution equipment, and is widely applied in urban and rural distribution networks. This product adopts a design with high-voltage load switches and high-voltage fuses immersed in transformer oil, featuring two structural forms: integrated tank and separate tank with the transformer body. The oil tank adopts a fully sealed structure, equipped with accessories such as an oil temperature gauge, oil level gauge, pressure gauge, pressure relief valve and oil drain valve to monitor the operating status of the transformer.     The substation is available in three power supply modes: ring main type, terminal type and power supply type.
