Application: Anticorrotion system (Patent ID: US20240117500A1)
The patent filed by Nippon Telegraph and Telephone Corp. describes an anti-corrosion system for utility poles, involving burying an anchor near the pole and connecting it to a guy wire with a guy wire rod. An electrode is also buried nearby, and a power supply, including a photovoltaic cell, provides an anti-corrosion current to prevent corrosion on the underground portion of the guy wire rod and anchor.
The system includes various configurations such as using a flexible photovoltaic panel, attaching a power supply to a guy wrap on the above-ground portion of the guy wire rod, and utilizing poorly soluble electrodes like composite metal oxide, platinum-titanium, or high silicon cast iron electrodes. Additionally, there are variations in the power supply, with some embodiments incorporating a commercial power supply with a DC-AC converter, and others using a pole-mounted transformer on the utility pole. The system aims to protect utility poles from corrosion by effectively distributing the anti-corrosion current through the cathode (underground portion of the guy wire rod and anchor) and anode (electrode) setup.
