If you look up at the big electrical towers that transmit high-voltage power over long distances, it is easy to understand the effects of the lack of maintenance. The brackets and connectors that attach insulators to the towers and cables to the insulators need to be designed to pivot and move. If a cable breaks free and hits the metal tower or another wire, the high voltage will cause a spark that will likely start a fire, especially in a region with so much dry terrain and vegetation. When the brackets get rusted or worn, they need to be replaced.
