An apparatus and a method for eliminating moisture from a superconductive cable line before operation are provided to evaporate moisture at low temperature and to discharge a non-condensed gas by injecting an inert gas into the cable of a vacuum state. An apparatus for eliminating moisture from a superconductive cable line(100) before operation includes a vacuum pump(200), a connection pipe(300), an inert gas supply source(400), regulating valves(501,502), and a heater(600). The connection pipe is extended from the vacuum pump to connect the vacuum pump and the superconductive cable line, and is connected to the superconductive cable line. The inert gas supply source is connected to the connection pipe adjacent to the vacuum pump, and injects an inert gas inside the connection pipe. The regulating valves regulate the vacuum pump, the inert gas supply source, and the superconductive cable line. The heater is installed at the outer circumference of the superconductive cable line. The inert gas sealed inside the superconductive cable line is heated as the superconductive cable line is heated by the external heater.
