IEVref: 466-03-14 ID: Language: en Status: Standard Term: catenary constant Synonym1: Synonym2: Synonym3: Symbol: Definition: constant in the catenary and parabola equations, geometrically represented by the radius of curvature at the lowest point of the span NOTE – The catenary constant ρ is equal to the quotient of the horizontal tension in the conductor To at a given temperature (see Figure 466-1) by its unit weight ω, which must take into account the ice or wind overloads, if applicable. $\rho =\frac{{T}_{\text{o}}}{\omega }$ Publication date: 1990-10 Source: Replaces: Internal notes: 2016-03-09: The reference to fig. 1 has been transferred to the note (in accordance with the published standard) and the figure number has been corrected to correspond to that of the figure. JGO 2016-03-21: Editorial correction: subscript to the horizontal tension in the conductor corrected to "o" for alignment with the figure. See correspondence RS and JS.
