The "messenger wire" hangs in a catenary curve, not a parabola. == Hanging ropes, chains, cables, if pulled down by a uniform force of gravity, assume the shape of a "catenary curve" not a parabolic curve. In the description of the electrical system, it talks about a messenger wire from which the conductor is suspended. It says this is curved as a parabola. It should say catenary curve.
