Oil-immersed high voltage current-limiting fuse  
This product is used in indoor power system of 50Hz AC, rated voltage from 10kV to 15kV, to power transformer and other electrical equipment from overloading and short-circuit. This oil-immersed fuse can be used independently, and also can be used in series with the oil-immersed fuse for overload protection to provide full-range protection for transformer.
