True or False: The purpose of spacers on transmission lines is to prevent conductors from wrapping together and to reduce vibration.

The statement about spacers on transmission lines serving to prevent conductors from wrapping together and to reduce vibration is true. Spacers are indeed installed on transmission lines primarily to maintain separation between conductors, which helps to prevent them from coming into contact with each other due to various forces such as wind, thermal expansion, or sagging. Additionally, spacers do play a role in reducing the vibrations that can occur in transmission lines, which is important for maintaining the structural integrity and functionality of the lines over time.

While some may argue that the effectiveness of spacers can vary based on installation or environmental conditions, this does not negate their primary role in preventing tangling and reducing vibration. Therefore, the correct answer is that the purpose of spacers on transmission lines is indeed to prevent conductors from wrapping together and to reduce vibration.
