What is the purpose of a tie wire in overhead line construction?

The purpose of a tie wire in overhead line construction is to secure conductors to insulators, which helps to prevent movement. This is crucial because, during inclement weather such as high winds, or when the conductor experiences thermal expansion and contraction, the tie wire holds the conductors in place. This stability ensures the safe and reliable operation of the power lines while also minimizing the risk of contact between conductors and other objects, which could lead to dangerous electrical faults or outages.

The tie wire serves a critical role in maintaining the integrity of the overhead line construction by providing necessary support and stabilization to the conductors as they hang from insulators. Properly secured conductors enhance the overall safety and functionality of the power distribution system. This makes the use of tie wire essential in ensuring that the components of the electrical infrastructure work harmoniously together.
