An overhead busbar system is a power distribution system in which cables are installed overhead. This system is typically used in industrial and commercial environments where there is a high demand for electricity. The main advantage of this system is that it is easier to maintain and repair and less likely to experience power outages. One of its drawbacks is that its installation cost can be higher than other types of power distribution systems. Also, the system is less suitable for areas with a lot of snow and ice, as the weight of the ice and snow can damage the cables.
