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. Serving as a key node within the Intelligent Power Distribution System for cable‑type distribution networks, this complete prefabricated assembly integrates High‑Voltage Switchgear, high‑voltage control, protection, voltage transformation as well as Low‑Voltage Distribution Cabinet. It can be combined with Transformer Automation Equipment and fits well within overall Industrial Automation Solutions, 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. While this unit uses oil‑immersed load switching, it can work cooperatively with external Vacuum Circuit Breaker for enhanced fault‑clearing capacity. The oil tank adopts a fully sealed str…
