I hope those cable lifters keep the wires absolutely horizontal. Otherwise the electrons will tend to pool at the cable dips.

On further thought, there should be a deliberate tilt associated with the lifter installation. At the low point an accessory "drain" device should be installed to extract and recycle the pooling electrons. This device should cost at least a few hundred dollars. And a monthly service charge could be added to allow the device to send the recycled electrons to a secure website for proper handling.
