Application
Fuse cutout can be installed on the high-voltage side of the transformer on the pole, where the transformer and the capacitor are connected to the line. The drop-out fuse effectively plays the role of overload protection and short-circuit protection in the circuit. At the same time, it can also be installed at the end of a long line or on a branch line. This approach can provide extended protection to areas that cannot be protected by relays. The structure of the drop-out fuse is not complicated but relatively simple, and it is also very economical in terms of price, and it does not require a lot of effort in future maintenance. Because the small size is convenient for installation, the fuse is used in the distribution network been widely used
