The role of drop-out fuses10kV equipment can be installed on the high-voltage side of the transformer on the pole, where the transformer and capacitor are connected to the line. The drop-out fuse can effectively protect the circuit from overload and short-circuit. At the same time, it can also be installed at the end of a long line or on a branch line, which can provide extended protection for areas that cannot be protected by relays.
