To improve the robustness of a water electrolysis system.SOLUTION: An insulated piping is composed of a double pipe comprising an inner pipe 130 which connects a water electrolysis stack and an auxiliary machine and inside which a fluid circulates, and an outer pipe 12 which is provided outside the inner pipe 130 via the inner pipe 130 and an outer pipe inner space 14. The outer pipe 12 has insulation properties. In the inner pipe 130, the water electrolysis stack and the auxiliary machine are insulated. A dry gas 13 where humidity is lower than or equal to a prescribed value is enclosed by a pressure of a fluid circulating inside the inner pipe 130 and a pressure higher than an atmosphere pressure in the outer pipe inner space 14 which is a space.SELECTED DRAWING: Figure 2 【課題】水電解システムのロバスト性向上を課題とする【解決手段】水電解スタックと、補機とを接続し、内部を流体が流通する内管１３０と、内管１３０の外側に、内管１３０、と外管内空間１４を介して設けられる外管１２と、によって構成される二重管で構成され、外管１２は絶縁性を有し、内管１３０において、水電解スタックと、補機とが絶縁されており、空間である外管内空間１４には、湿度が所定の値以下である乾燥気体１３が、内管１３０の内部を流通する流体の圧力、及び、大気圧よりも高い圧力で封入されていることを特徴とする。【選択図】図２
