SAMCEF POWERLINES & SUBSTATIONS is our professional solution dedicated to simulation of the mechanical behavior of the electricity supply network. It computes static configurations when imposing either cable length, tension at some point or maximum sag. From there, one can compute responses to static loads like frost, temperature changes or wind, as well as to dynamic ones, produced e.g. by cable breaks, or electrodynamic forces, when a short circuit occurs. All these loads can be applied to cables and rigid bus bars. Pylons can also be represented in order to take their inertia and stiffness into account in the computation.
