Description

Technical Field

Background Art

With the rapid development of society, power equipment is being used more and more widely, and the demand for electricity is increasing. During the construction of transmission lines, whether the transmission lines are tightened is directly related to the normal use of the entire power line. If the transmission lines are too loose, they will swing due to excessive sag, collide with each other and cause a short circuit, thus affecting the normal supply of electricity.
