The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid. ## Claims ### Claim 1 A cable for an electrical power delivery station, the cable comprising: a sheath with an axial pathway running a length of the cable between a first end of the cable and a second end of the cable;
