They are usually quite expensive and require very low operating temperatures.

Normal conductors have resistance which restricts the flow of electricity and wastes some of the energy as heat. The resistance increases with the length of the conductor. Superconductors have close to zero or zero resistance and a few other properties, but the resistance is the most important one because it means electricity can flow more efficiently through it. The drawback is that all the superconductors we know of today have to be cooled down to EXTREMELY low temperatures to achieve superconductivity.

materials are often birttle and hard to shape into wires
superconductors, they have no resistance.
Because at present all superconductors must be super-cooled in a coolant such as liquid nitrogen to become superconductors.
