Fix False Dead End Fast: Compare Solutions

A false dead end is a specific configuration where the conductors terminate or anchor at a structure. It occurs at an intermediate structure where conductors anchor for mechanical reasons. A false dead end helps to handle mechanical stresses such as tension and sag. It creates an illusion that the line does not continue beyond that point when it actually does. It maintains the electrical continuity of the transmission line to extend beyond the point. The primary purpose of the false dead end is to provide extra mechanical support. Its design offers flexibility in the design and construction of transmission lines. They also allow operators to divide the line into manageable sections without disrupting the flow. They work at intermediate points along the line, terrain challenges and load distribution. A false dead end helps reduce the risk of conductor failure due to excessive sag.
