I have seen this as well. The 5G infrastructure is being installed everywhere now during the Covid-19 lockdown. These cables are being installed on existing hydro poles about half way up the pole. It is a single cable, and is thicker in diameter than the existing hydro wires. Electrical boxes, and what looks similar to large inline fuses, and other gadgets are spliced into this cable. Soon you will see the 5G antennas on top of the poles, and worst of all - SURVIELANCE CAMERAS everywhere.
