Is the bisect tension of a conductor exerted on a 60° corner pole equal to line tension?

• A. True
• B. False
• C. It varies depending on conditions
• D. Only for certain angles

Answer: (A)

In the context of powerline construction and tension in conductors, the bisect tension at a corner pole is indeed equal to the line tension when the angle at the pole is 60 degrees. This is based on the geometry of forces acting on the conductor.

When a conductor makes a corner, the tension is influenced by how the conductor is oriented. At a 60° angle, the tension within the conductor resulting from the weight and other forces is bisected evenly due to the symmetry of the angle. Thus, the tension on either side of the corner pole is balanced, leading to the conclusion that the bisect tension equals the line tension.

This relationship holds true specifically for this angle because of the unique properties of right triangles and the sine rules applicable to such configurations. Other angles might not exhibit this same property, which is why different conditions could lead to a different assessment in those scenarios.
