The present invention relates to a heat sink busbar and a switch gear having the same. In particular, on an upper surface of the busbar, a heat sink is formed to widen an outer circumferential length (an air contacting surface) of the busbar. Therefore, efficiency of heat dissipation is increased. The heat sink busbar and an insulator are stably fixed inside the closure by a fixing bracket, bolts, and nuts. The heat sink busbar can be joined and connected using the joining bracket, bolts, and nuts in a simple manner. Therefore, the heat sink busbar has a simple structure; time for manufacturing the heat sink busbar can be reduced. |
