What is a common method for removing ice from power lines?

Using hot water spray or thermal blankets is an effective method for removing ice from power lines due to the principles of heat transfer. When ice forms on power lines, it creates additional weight and can lead to dangerous conditions, including power outages or line breakage. By applying hot water, the heat effectively melts the ice, allowing it to slide off without causing damage to the line or risking safety.

Using thermal blankets also provides a controlled means of applying heat directly to affected areas, preventing ice from reforming as well as minimizing the risk of further electrical hazards. This method is both efficient and safer than other approaches, making it a common practice among linemen facing ice accumulation issues.

In contrast, using a chainsaw or leaning on the lines can be unsafe and potentially damaging to the equipment and the linemen. High-pressure water alone might not be effective in melting the ice, especially in very cold conditions, as it could freeze again quickly. Thus, the chosen solution leverages thermal dynamics to address the problem in a targeted and safe manner.
