B&W is the right choice here for sure but it still needs something to make it more interesting. Unfortunately, this requires some experimental editing. I inverted the image so that black became white and vice versa. This makes it appear to be strongly backlit and reveals a thick coil like those newish very efficient spiral light bulbs beneath the loops of telephone line. Add a reasonably unsubtle vignette to enhance the strong glow of backlighting and the image becomes more interesting.
