I'm looking at suspending some low volatage (<30V) lighting with a 7x7 304 stainless steel aircraft cable. I also want to run 30V DC through the cable to power the light. So the suspension cable is also supplying the power. I will be running 4 separate cables (only 2 will be used to supply power). The closest cables will be about 2 feet apart. To keep the conductivity high I want to replace the stainless steel 1x7 core of the cable with a 1x7 copper strand. This will be used indoors in office buildings, grocery stores and the like. Will there be any corrosion issues with the copper or stainless steel wires?
