What can be affected if a transmission line exceeds its temperature threshold?

When a transmission line exceeds its temperature threshold, the structural integrity of the line can be compromised. High temperatures can cause thermal expansion in the materials used in the transmission line, which may lead to sagging, increased tension, or even physical damage to the line if it stretches beyond its design limits. As the materials of the line degrade, their ability to support the electrical load diminishes, potentially resulting in failures or outages.

In the context of electrical infrastructure, maintaining the structural integrity of transmission lines is crucial for safe and reliable operation. If the physical structure is damaged, it can pose risks not only to the infrastructure itself but also to public safety and service reliability. Other aspects, like efficiency in power distribution, power output, and financial returns, can be indirectly affected but do not directly relate to the immediate physical condition of the transmission line in the same critical manner as structural integrity does.
