What type of equipment would be used to disconnect lines or equipment in a substation?

The fused cutout switch is specifically designed for disconnecting lines or equipment in substations. Its primary function is to provide a means of isolating sections of the electrical system for maintenance or in the event of a fault. The switch operates by physically opening the circuit, allowing for safe access to the equipment downstream while preventing electrical current flow.

The integral feature of a fused cutout switch includes fuses that protect the circuit from overloads or shorts. When a fault occurs, the fuse blows, and the switch can then be opened to safely isolate the faulted section. This capability is critical for maintaining safety and ensuring that repair work can be performed without risking exposure to live electrical components.

Other options, while important in their respective functions, do not serve the primary purpose of disconnecting lines or equipment in the way that a fused cutout switch does. Lightning arrestors, for instance, are used for protecting equipment from voltage spikes, and reclosers are designed to automatically restore service after a fault is cleared rather than isolating equipment. A hydraulic lift is not directly involved in electrical systems and serves a mechanical function unrelated to disconnection.
