Abstract :Abstract. Due to the high amount of normal and short-circuit current in power systems, using of busbars is inevitable. The combination of copper and aluminum and aluminum copper alloys as conductor are used. One of the most important points in the design of power systems is the right choice of conductor.The proper selection of conductor is dependent on several factors such electrical, mechanical, chemical, environmental and weather conditions. In order to choose a conductor, amount of current, height from sea level, temperature, voltage level, level of short circuit current and it s duration, The positioning of busbars and number of them in each phase, to be bared or not to be and resistivity of any conductor must be assessed. for better longevity of the busbar and flow continuity of current at nominal value, corresponding guidelines must be done, also the distance between the equipment are energized and distance between energized equipment and ground should be noted.
