A fluid detection cable is described for use in detecting the presence of leaks or other conductive fluids in areas where a particular fluid is not desired. Sensing leads in the fluid detection cable have a center conductor that may be surrounded with a non-porous conductive polymer coating that protects the conductors from corrosive fluids. A non-conductive polymer at least partially surrounds the sensing leads so that a fluid transmission path allows fluid to contact the conductive polymer. The non-conductive polymer may be porous to provide a fluid transmission path. Fluid transmission paths may also be structurally formed in the non-conductive polymer. The non-conductive polymer protects the sensing leads from false alarms that would occur if the conductive polymer were to be in contact with non-fluid conductive surfaces. The cable may also include monitor leads that are conductors coated with, or embedded in, non-conductive non-porous polymers. The sensing leads and monitor leads are joined or formed together in various shapes and configurations including shapes and sizes conforming to low cost industry standard telephone wires and network cables that allow industry standard connectors, tools, and accessories to be used with the fluid detection cable. The cable may be formed to provide a trough that is capable of collecting fluid. The cable is then connected to a control system that detects a fluid that is in contact with the sensing leads of the cable.
