Oct 27, 2013 · A hollow section has higher stiffness than a solid rod of equivalent current-carrying capacity, which allows a greater span between busbar supports in outdoor switch yards. A busbar may either be supported on insulators, or else insulation may completely surround it.Location: Panipat, Haryana, India

standards for support span, but the bending stress considered in its calculation is very low (15.9 Mpa). There are other references also who have listed the maximum support span. In this paper equations for calculating the maximum span using maximum bending stress are given. Safety of the design is checked using maximum deflection. A

A hollow section also has higher stiffness than a solid rod of equivalent current-carrying capacity, which allows a greater span between busbar supports in outdoor electrical switchyards. A busbar must be sufficiently rigid to support its own weight, and forces imposed by mechanical vibration and possibly earthquakes , as well as accumulated precipitation in outdoor exposures.
