Installations made with busbars.
They are used in factory halls in the event of changes in the scope and type of production, necessitating regrouping, replacement or installation of new machines. The constant connection of machines to the mains with cables or pipes arranged in pipes makes it difficult to move the machine. Busbars made of ready-made elements joined together, make possible branches from them 1 m without the need to turn off the voltage.
Distance between support points (suspensions) busbars should not exceed 6 in. The railroad can be placed on supports, outriggers or suspended from ropes or rods. Fuse boxes should be attached to additional supports, to prevent swaying of the busbar when replacing the fuse link. The installation of busbars should be carried out in accordance with the manufacturer's instructions.
For powering mobile devices and receivers such as overhead cranes or electric hoists and in rooms with a large number of frequently moved machines and tools, slide rail cables are used.
