PIPE TYPE SOLID INSULATION CABLE SYSTEM, METHOD OF CONSTRUCTING PIPE TYPE SOLID INSULATION CABLE SYSTEM AND METHOD OF COOLING PIPE TYPE SOLID INSULATION CABLE SYSTEM

摘要

A pipe type solid insulation cable system includes a plurality of solid insulation cables; a plurality of steel pipes in which the plurality of solid insulation cables are inserted, respectively; and a refrigerant circulation path that includes a plurality of refrigerant pipes, which are provided to be adjacent to the plurality of steel pipes, respectively, circularly connected with each other to circulate a refrigerant therein, wherein the pipe type solid insulation cable system is configured to indirectly cool the plurality of solid insulation cables in the plurality of steel pipes, respectively, by cooling at least a part of a periphery of each of the plurality of steel pipes by the refrigerant circulation path without flowing the refrigerant in the plurality of steel pipes.
