A flow-through cable for transmitting information (20) is provided. The cable includes a jacket (22) having a length and an information conducting core (26) coaxially received within the jacket. A first insulation layer (24) surrounds the information-conducting core and has a dielectric strength. The cable further includes a first conduit (28) disposed within the jacket. The first conduit is adapted to permit a compound to flow therethrough and is chemically permeable to permit at least a portion of the compound to diffuse through the first conduit.
