Q1: What is the function of a drop-out fuse cutout?
A1: It protects distribution transformers and lines from overloads and short circuits. Once a fault occurs, the fuse blows and the fuse holder drops, creating a visible disconnection point.
Q2: What is the voltage range of your fuse cutouts?
A2: Our products cover 10kV to 40.5kV, with rated currents of 100A and 200A.
Q3: Can the fuse cutout be used outdoors?
A3: Yes, all models are designed for outdoor use with strong insulation, weather resistance, and long service life.
Q4: What standards do your products comply with?
A4: They comply with IEC and GB standards for high-voltage fuse cutouts, ensuring safety and reliability.
Q5: Where are these products commonly applied?
A5: They are used in urban and rural power distribution networks, substations, and industrial facilities.
