Mobile equipment needs to constantly change positions due to movement, and at each different position, it must be able to obtain power supply at any time, otherwise it cannot continue moving. At this point, busbar came into being. Several conductors are laid parallel along the running track of the mobile equipment and connected to the power supply. On the mobile equipment, a current collector that can draw power from the conductors is installed. In this way, when the equipment moves, the current collector moves synchronously with the equipment and obtains power from the conductors at any time to supply the equipment, allowing it to continue moving. The device composed of these conductors and current collectors is called a busbar.
The power supply busbar device consists of three main components: the sheath, conductor, and current collector, as well as some auxiliary components.
1. Sheath: It is a semi-enclosed tubular component and the main part of the busbar. Inside, 3-16 bare guide rails can be embedded as power supply conductors as needed, and each guide rail is insulated from each other to ensure the safety of power supply. It also effectively prevents electric shock accidents for maintenance personnel during live maintenance. The length of each conduit produced by the manufacturer varies, and they can be connected to any required length. Ordinary conduits are made in straight shapes, and can also be made into arc shapes or other special shapes according to special requirements.
2. Conductor: The main material is copper. According to its cross-sectional area, common ones are 10 square millimeters, 16 square millimeters, and 25 square millimeters.
3. Current collector: It is a set of brush shells running inside the conduit, driven by a fork (or traction chain, etc.) installed on the electrical mechanism (such as a crane, trolley, electric hoist, etc.), making it run synchronously with the electrical mechanism and transmit the electrical energy from the guide rails and brushes to the motor or other control elements. The number of poles of the current collector brushes ranges from 3 to 16, corresponding to the number of poles of the guide rails in the conduit.

1. Safety: The shell of the power supply busbar is made of engineering plastic with high insulation performance. The protection level of the shell can reach IP13 and IP55 as needed, which can protect against rain, snow, ice attacks, and contact with hanging objects. The product has withstood various environmental conditions. Insulation
